POWER MANAGEMENT SRAM GLOBAL BIT LINE PRECHARGE CIRCUIT

摘要

A domino static random access memory (SRAM) having one or more SRAM memory cells connected with a local bit line is disclosed. The SRAM may include a precharge device connected between a voltage supply and the local bit line, and global bit line (GBL) discharge logic connected between a local bit line and a GBL. The GBL discharge logic transfers a logic value of the local bit line to the GBL during a read operation. GBL precharge logic connects the GBL to a global precharge input. The GBL precharge logic is adapted to draw the GBL to a precharge voltage above a discharge voltage and below a supply voltage during a precharge operation.
