It is fabricated using silicon-gate CMOS process technology. The LH5P832 uses convenient on-chip refresh circuitry with a DRAM memory cell for pseudo static operation. This simplifies external clock inputs, while providing the same simple, non-multiplexed pinout as industry standard SRAMs. Moreover, due to the functional similarities between PSRAMs and SRAMs, many 32K × 8 SRAM sockets can be filled with the LH5P832 with little or no changes. The advantage is the cost savings realized with the lower cost PSRAM.
