ABSTRACT:
A multi-port memory cell includes a first SRAM element having a first pair of access transistors electrically coupled to a pair of FIFO write bit lines. A second dual-port SRAM element is also provided. This second dual-port SRAM element has a second pair of access transistors electrically coupled to a pair of FIFO read bit lines and a third pair of access transistors electrically coupled to a pair of memory read bit lines. A direct path data transfer circuit is provided. This transfer circuit is configured to support a unidirectional data transfer path that extends from first storage nodes within the first SRAM element to second storage nodes within the second dual-port SRAM element. This transfer circuit is also responsive to a direct path word line signal.
