Bit line write assist for static random access memory architectures
Abstract:
SRAM devices are disclosed that utilize write assist circuits to improve the logical transitions of bit lines. In one embodiment, an SRAM device includes a pair of complimentary bit lines traversing a memory cell array for writing data to memory cells. The bit lines have a first end and a second end. A pair of complimentary write drivers is proximate to the first end of the bit lines that writes to the bit lines. A write assist circuit is proximate to the second end of the bit lines that receives a pre-charge signal to assist the write drivers in transitioning the bit lines from a logical zero state to a logical one state. The write assist circuit also receives a boost signal to assist the write drivers in transitioning the bit lines from a logical one state to a logical zero state.
