Atomic read/write support in a multi-module memory configuration










Image Number 3 for United States Patent #7660951.

Efficient transfer of data to and from random access memory is described. Multiple request sources and a memory system comprise memory modules having memory banks, each bank containing rows of data. The retrieval comprises transferring all data pursuant to a given request by one source before any data is transferred pursuant to a subsequent request from said second source. This retrieval is achieved using a memory arbiter that implements an algorithm for atomic read/write. Each bank is assigned a FIFO buffer by the arbiter to store access requests. The access requests are arbitrated, and an encoded value of a winner of arbitration is loaded into the relevant FIFO buffer(s) before choosing the next winner. When an encoded value reaches the head of the buffer, all associated data is accessed in the given bank before accessing data for another request source.
