Abstract
A synchronous single port random access memory comprises a core,of memory cells,arranged as rows and columns. The rows are addressed by a row decoder,and the memory cell outputs are connected as columns to a column decoder and multiplexer,The decoder and multiplexer,selects groups of memory cells,from the addressed row and connects these to sense amplifiers,Changes in address are propagated immediately to the core,so that the selected memory cells,are connected as quickly as possible and without any fixed delays to the sense amplifiers,Similarly, a read clock “rclk” enables the sense amplifiers,immediately upon becoming active.
