Abstract
In an example, a method of memory repair may include receiving, by a memory repair unit, a plurality of memory identifiers. The method may include determining, by the memory repair unit, that a first memory identifier of the plurality of memory identifiers corresponds to a first memory of a plurality of memories. The method may include determining, by the memory repair unit, that a second memory identifier corresponds to a second memory of the plurality of memories. The method may include outputting, by the memory repair unit, in parallel: a first value to a repair enable input of the first memory, and a second value to a repair enable input of the second memory.
Claims27
A method of memory repair, comprising:
- receiving, by a decoder, a first memory identifier, wherein the first memory identifier corresponds to a first memory;
- determining, by the decoder, that the first memory identifier corresponds to the first memory;
- outputting, by the decoder, a first value on a first conductive path corresponding to the first memory based on determining that the first memory identifier corresponds to the first memory;
- receiving, by an accumulator, the first value on the first conductive path corresponding to the first memory;
- storing, by the accumulator, the first value corresponding to the first memory;
- and
- outputting, by the accumulator, the first value on a second conductive path connected to a first repair enable input of the first memory.
An apparatus for memory repair, comprising:
- a plurality of memories that includes a first memory;
- a repair information memory storing a first memory identifier that corresponds to the first memory;
- and
- a memory repair unit communicatively coupled to the repair information memory and the plurality of memories, wherein the memory repair unit comprises a decoder and an accumulator,
- wherein the decoder is configured to:
- receive the first memory identifier stored in the repair information memory;
- determine that the first memory identifier corresponds to the first memory;
- and output a first value on a first conductive path corresponding to the first memory based on the determination that the first memory identifier corresponds to the first memory, and
- wherein the accumulator is configured to:
- receive the first value on the first conductive path corresponding to the first memory;
- store the first value corresponding to the first memory;
- and output the first value on a second conductive path connected to a first repair enable input of the first memory.
An apparatus, comprising:
- a repair information memory;
- a plurality of memories;
- and
- a memory repair unit communicatively coupled to the repair information memory and the plurality of memories, wherein the memory repair unit is configured to:
- receive, from the repair information memory, a plurality of memory identifiers, wherein the plurality of memory identifiers includes a first memory identifier and a second memory identifier, wherein each memory identifier of the plurality of memory identifiers corresponds to a respective memory of the plurality of memories, wherein the first memory identifier corresponds to a first memory of the plurality of memories and the second memory identifier corresponds to a second memory of the plurality of memories;
- determine that the first memory identifier corresponds to the first memory;
- determine that the second memory identifier corresponds to the second memory;
- and
- output:
- a first value to a repair enable input of the first memory;
- and
- a second value to a repair enable input of the second memory.
