IDT71256 is a type of static random-access memory (SRAM) chip manufactured by Integrated Device Technology, Inc. (IDT). It is a high-speed, low-power CMOS (complementary metal-oxide-semiconductor) memory device commonly used in various electronic systems for storing data temporarily. “71256” in the part number typically indicates a 256-kilobit (Kb) memory capacity. This means the SRAM chip can store 256 kilobits (32 kilobytes) of data.

Description
IDT71256 is a 262,144-bit high-speed static RAM organized as 32K x 8. It is fabricated using high-performance, high-reliability CMOS technology. Address access times as fast as 20ns are available with power consumption of only 350mW (typ.). The circuit also offers a reduced power standby mode. When CS goes HIGH, the circuit will automatically go to and remain in, a low-power standby mode as long as CS remains HIGH. This capability provides significant system level power and cooling savings. The low-power (L) version also offers a battery backup data retention capability where the circuit typically consumes only 5μW when operating off a 2V battery.
