Abstract
A static random access memory (SRAM) system includes a plurality of SRAM storage cells, each of the plurality of SRAM storage cells coupled to a respective read bit line, and a dynamic keeper coupled to the read bit line. The dynamic keeper includes a first keeper to support a read operation at a first temperature range, and a second keeper to support the read operation at a second temperature range, and a temperature-sensitive control circuit to select the first keeper or the second keeper based on temperature.
