Buffer control system and method for a memory system having outstanding read and write request buffers

An apparatus, comprising:

• a controller configured to determine a number of outstanding memory requests of a first type issued to a memory and determine a number of outstanding memory requests of a second type issued to the memory, the controller further configured to control issuance of memory requests of the first type to the memory based, at least in part, on the number of outstanding memory requests of the first type and to control issuance of memory requests of the second type to the memory based, at least in part, on the number of outstanding memory requests of the second type.

An apparatus, comprising:

• a request queue configured to receive memory requests of a first type and memory requests of a second type, the request queue configured to selectively provide the memory requests of the first type according to a first flow control signal and to selectively provide the memory requests of the second type according to a second flow control signal;
• and
• a flow control unit configured to determine a number of outstanding memory requests of the first type and to determine a number of outstanding memory requests of the second type, the flow control unit further configured to provide the first flow control signal and the second flow control signal, the first flow control signal based, at least in part, on the number of outstanding memory requests of the first type and the second flow control signal based, at least in part, on the number of outstanding memory requests of the second type.
