Context data associated with interrupted program operations can be received at the first controller component. A control sequence based on the context data can be generated at the first controller component. The control sequence can indicate how a second controller component associated with the memory sub-system interacts with a memory component of the memory sub-system to perform the read operation and to resume the interrupted program operations. The control sequence can further specify one or more additional operations that are associated with copying data of the interrupted program operations between first and second memory locations of the memory component. The control sequence can be provided to the second controller component. ## Claims ### Claim 1 A method comprising: receiving, at a first controller component associated with a memory sub-system, an indication that one or more program operations have been interrupted as a result of a read operation; receiving, at the first controller component, context data associated with the one or more interrupted program operations; generating, at the first controller component, a control sequence based on the context data, wherein the control sequence indicates how a second controller component associated with the memory sub-system interacts with a memory component of the memory sub-system to perform the read operation and to resume the one or more interrupted program operations, wherein the control sequence further specifies one or more additional operations that are associated with copying data of the one or more interrupted program operations between first and second memory locations of the memory component of the memory sub-system; and providing the control sequence to the second controller component. ### Claim 2 (depends on 1) The method of claim 1, wherein the first controller component comprises firmware of a controller of the memory sub-system, and the second controller component comprises a hardware component of the controller of the memory sub-system. ### Claim 3 (depends on 1) The method of claim 1, wherein the context data identifies a point of the one or more interrupted program operations at which the one or more interrupted program operations have been interrupted. ### Claim 4 (depends on 1) The method of claim 1, wherein the context data identifies an amount of the data of the one or more interrupted program operations that has been written to memory cells of the memory component prior to interruption of the one of the program operations. ### Claim 5 (depends on 1) The method of claim 1, wherein the one or more additional operations correspond to retaining data associated with the one or more interrupted program operations, the retained data being used to resume the one or more interrupted program operations. ### Claim 6 (depends on 1) The method of claim 1, wherein the read operation stores read data from one or more memory cells of the memory component at the first memory location. ### Claim 7 (depends on 6) The method of claim 6, wherein the additional operations that are associated with copying data comprise operations to: copy the data of the one or more interrupted program operations from the first memory location to the second memory location; retrieve the read data using the first memory location; and provide the read data to the second controller component using the first memory location. ### Claim 8 (depends on 7) The method of claim 7, wherein the additional operations that are associated with copying data further comprise one or more operations to: copy the data of the one or more interrupted program operations from the second memory location to the first memory location. ### Claim 9 (depends on 1) The method of claim 1, wherein the control sequence is further based on a type of the memory component of the memory sub-system. ### Claim 10 (depends on 9) The method of claim 9, wherein type of the memory component identifies one or more available resources of the memory component. ### Claim 11 (depends on 10) The method of claim 10, wherein the one or more available resources of the memory component comprise a number of buffers in which to store data associated with program operations or read operations. ### Claim 12 A system comprising: a memory;
