Abstract
A memory and method of performing a write operation in a memory are disclosed. In one aspect of the disclosure, the memory includes a memory cell, a pair of bit lines coupled to the memory cell, a multiplexer, and a pull-up circuit coupled to the multiplexer. The multiplexer may be configured to select the pair of bit lines coupled to the memory cell during the write operation. To increase the write performance of the memory cell, the pull-up circuit is configured to select which of the pair of bit lines is a non-zero bit line during the write operation and to clamp the non-zero bit line through the multiplexer to approximately a power rail voltage. Thus, the pull-up circuit may increase the voltage difference between the non-zero bit line and the zero bit line during the write operation and thus decrease the area and power consumed by a boost capacitance.
