System and method for enabling/disabling sram banks for memory access

Abstract

A system and method are provided which enable a data carrier, such as a BIT line, to be held to a desired value while performing a memory access (e.g., a read or write operation) of SRAM in an efficient manner. In a preferred embodiment, cross-coupled PFETs are implemented to hold the BIT line to a desired value during a memory access of SRAM. As a result, a preferred embodiment enables a BIT line to transition from a high voltage value to a low voltage value free from conflict. That is, in a preferred embodiment, a holder PFET is not attempting to hold the BIT line high, while the SRAM or outside source (e.g., a “writing source”) is attempting to drive the BIT line to a low voltage value. Also, in a preferred embodiment, the BIT and NBIT lines (i.e., a complementary data carrier) can be driven to “true” low and “true” high voltage values. Accordingly, in a preferred embodiment, complex circuitry, such as a sense amp, is not required to detect whether a value on the lines is a logic 0 or logic 1. Therefore, a preferred embodiment enables memory access requests (e.g., read and write operations) to be serviced in a more timely manner than is achieved utilizing prior art implementations. Furthermore, a preferred embodiment requires less power consumption than is required for prior art implementations. Moreover, a preferred embodiment utilizes fewer components, and therefore consumes less surface area than in prior art implementations.
