DATA-CONTROLLED AUXILIARY BRANCHES FOR SRAM CELL

摘要

A circuit includes a first inverter, a second inverter, a first auxiliary branch and a second auxiliary branch. The first and second inverters are cross-coupled to form a first storage node and a second storage node. The first auxiliary branch is coupled to the first storage node and configured to assist the first inverter in holding data based on data stored at the second storage node during a read operation, and assist the first inverter in flipping data based on data to be written to the first storage node during a write operation. The second auxiliary branch is coupled to the second storage node and configured to assist the second inverter in holding data based on data stored in the first storage node during the read operation, and assist the second inverter in flipping data based on data to be written to the second storage node during the write operation.
