PseudoSRAM

Pseudo SRAM (Static Random Access Memory) consists of a DRAM macro core with a traditional SRAM interface; an on-chip refresh circuit that frees the user from the need to take care of this task. Comparing to traditional CMOS SRAM, PSRAM has advantage in higher density, higher speed, smaller die size, and DRAM compatible process.
