DESCRIPTION

The IDT71V256SB is a 262,144-bit high-speed static RAM organized as 32K x 8. The improved VIH (1.8V) makes the inputs compatible with 2.5V logic levels. The IDT71V256SB is otherwise identical to the IDT71V256SA.

The IDT71V256SB has outstanding low power characteristics while at the same time maintaining very high performance. Address access times of as fast as12 ns are ideal for tag SRAM in secondary cache designs.
