ABSTRACT:
A serial scan chain extends into an array of SRAM cells within a multi-ported memory system for allowing serial introduction of write data into the SRAM cells and serial read-back of the data. Initial data may be pre-loaded into the SRAM cells by way of the serial scan chain before being read parallel-wise in response to read requests submitted through any of multiple, parallel data access ports of the system.
