Abstract
A First-In First-Out (FIFO) shift register memory system (10) with a plurality of memory word registers (50) having data inputs connected to a common data-in bus (16), and a plurality of data outputs connected to a common data-out bus (22). A write address ring counter (32) is responsive to first transitions (164, 168) of a write pulses to increment to successive stages (32) therein. A plurality of latches (154) are each responsive to a second transition (166) to latch in a write address bit. The latches (154) are each enabled to write the address bit to a respective memory register (50) upon a successive first transition (168).
