Write tracking for memories

A system comprising:

• a memory;
• a memory controller comprising a write tracking buffer, the memory controller to:
• receive a write request bound for the memory;
• store an entry associated with the write request in the write tracking buffer, the entry indicating progress of completion of the write request;
• determine an access pattern of the memory, wherein the access pattern indicates a high or a low write bandwidth of the memory based on how full the write tracking buffer is;
• responsive to determining that the access pattern indicates the low write bandwidth, allow write suspension to a bank of the memory with which the write request is associated;
• determine that the write request will complete within a threshold length of time;
• in response to determining that the write request will complete within the threshold length of time, disallow the write suspension to the bank of the memory and execute the write request;
• while execution of the write request is in-progress, receive a read request associated with the bank of memory;
• responsively suspend the write request that the execution of which is in-progress if the access pattern indicates the low write bandwidth;
• allow the read request to complete;
• after completion of the read request, resume the execution of the write request;
• and
• completing the write request.

A non-transitory machine-readable storage medium encoded with instructions, the instructions that, when executed, cause a processor to:

• receive a write request bound for a memory;
• store an entry associated with the write request in a write tracking buffer, the entry indicating progress of completion of the write request;
• determine, based on a number of entries stored in the write tracking buffer, an access pattern of the memory, wherein the access pattern indicates a high or a low write bandwidth of the memory;
• responsive to determining that the access pattern indicates the low write bandwidth, allow write suspension to a bank of the memory with which the write request is associated;
• determine that the write request will complete within a threshold length of time;
• in response to determining that the write request will complete within the threshold length of time, disallow the write suspension to the bank of the memory and execute the write request;
• while execution of the write request is in-progress, receive a read request associated with the bank of memory;
• responsively suspend the write request that the execution of which is in-progress if the access pattern indicates the low write bandwidth;
• allow the read request to complete;
• and
• after completion of the read request, resume the execution of the write request;
• and
• complete the write request.
