INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract An example system includes a memory device and a processing device, operatively coupled with the memory device. The processing device is configured to perform operations including: determining that a write request references a partially aligned translation unit; identifying a first entry in a translation map, such that the first entry identifies a first physical block of the memory device, such that the first physical block is mapped to the partially aligned translation unit; creating a second entry in the translation map, wherein the second entry identifies a second physical block of the memory device, wherein the second physical block is mapped to the partially aligned translation unit; linking, in the translation map, the first entry and the second entry; and writing a subset of data corresponding to the partially aligned translation unit to a first portion of the second physical block. ## Claims ### Claim 1 A system comprising: a memory device; and a processing device, operatively coupled with the memory device, to perform operations comprising: determining that a write request references a partially aligned translation unit; identifying a first entry in a translation map, wherein the first entry identifies a first physical block of the memory device, wherein the first physical block is mapped to the partially aligned translation unit; creating a second entry in the translation map, wherein the second entry identifies a second physical block of the memory device, wherein the second physical block is mapped to the partially aligned translation unit; linking, in the translation map, the first entry and the second entry; and writing a subset of data corresponding to the partially aligned translation unit to a first portion of the second physical block. ### Claim 2 (depends on 1) The system of claim 1, wherein the partially aligned translation unit comprises a predefined number of logical pages and represents a base granularity of data supported by the memory device. ### Claim 3 (depends on 1) The system of claim 1, wherein determining that the write request references the partially aligned translation unit further comprises: determining that a starting logical address specified by the write request does not correspond to a starting address of the partially aligned translation unit. ### Claim 4 (depends on 1) The system of claim 1, wherein determining that the write request references the partially aligned translation unit further comprises: determining that an ending logical address specified by the write request does not correspond to an ending address of the partially aligned translation unit. ### Claim 5 (depends on 1) The system of claim 1, wherein the partially aligned translation unit is a last element of a set of translation units specified by the write request. ### Claim 6 (depends on 1) The system of claim 1, wherein the operations further comprise: determining that the first physical block comprises existing valid data. ### Claim 7 (depends on 1) The system of claim 1, wherein the operations further comprise: designating the first physical block and the second physical block for garbage collection. ### Claim 8 A method comprising: determining, by a processing device, that a write request references a partially aligned translation unit; identifying a first entry in a translation map, wherein the first entry identifies a first physical block of a memory device, wherein the first physical block is mapped to the partially aligned translation unit; creating a second entry in the translation map, wherein the second entry identifies a second physical block of the memory device, wherein the second physical block is mapped to the partially aligned translation unit; linking, in the translation map, the first entry and the second entry; and writing a subset of data corresponding to the partially aligned translation unit to a first portion of the second physical block. ### Claim 9 (depends on 8) The method of claim 8, wherein the partially aligned translation unit comprises a predefined number of logical pages and represents a base granularity of data supported by the memory device. ### Claim 10 (depends on 8) The method of claim 8, wherein determining that the write request references the partially aligned translation unit further comprises: determining that a starting logical address specified by the write request does not correspond to a starting address of the partially aligned translation unit. ### Claim 11 (depends on 8) The method of claim 8, wherein determining that the write request references the partially aligned translation unit further comprises: determining that an ending logical address specified by the write request does not correspond to an ending address of the partially aligned translation unit. ### Claim 12 (depends on 8) The method of claim 8, wherein the partially aligned translation unit is a last element of a set of translation units specified by the write request. ### Claim 13 (depends on 8) The method of claim 8, further comprising: determining that the first physical block comprises existing valid data. ### Claim 14 (depends on 8) The method of claim 8, further comprising: designating the first physical block and the second physical block for garbage collection. ### Claim 15 A non-transitory computer-readable storage medium comprising executable instructions that, when executed by a processing device, cause the processing device to: determining that a write request references a partially aligned translation unit; identifying a first entry in a translation map, wherein the first entry identifies a first physical block of the memory device, wherein the first physical block is mapped to the partially aligned translation unit; creating a second entry in the translation map, wherein the second entry identifies a second physical block of the memory device, wherein the second physical block is mapped to the partially aligned translation unit; linking, in the translation map, the first entry and the second entry; and writing a subset of data corresponding to the partially aligned translation unit to a first portion of the second physical block. ### Claim 16 (depends on 15) The non-transitory computer-readable storage medium of claim 15, wherein the partially aligned translation unit comprises a predefined number of logical pages and represents a base granularity of data supported by the memory device. ### Claim 17 (depends on 15) The non-transitory computer-readable storage medium of claim 15, wherein determining that the write request references the partially aligned translation unit further comprises: determining that a starting logical address specified by the write request does not correspond to a starting address of the partially aligned translation unit. ### Claim 18 (depends on 15) The non-transitory computer-readable storage medium of claim 15, wherein the partially aligned translation unit is a last element of a set of translation units specified by the write request. ### Claim 19 (depends on 15) The non-transitory computer-readable storage medium of claim 15, further comprising executable instructions that, when executed by the processing device, cause the processing device to: determine that the first physical block comprises existing valid data. ### Claim 20 (depends on 15) The non-transitory computer-readable storage medium of claim 15, further comprising executable instructions that, when executed by the processing device, cause the processing device to: designate the first physical block and the second physical block for garbage collection.
