x True Dual-Ported memory cells which allow simultaneous
access of the same memory location
x High-speed access
– Commercial: 15/20ns (max.)
– Industrial: 20ns (max.)
x Low-power operation
– IDT70V37L
Active: 440mW (typ.)
Standby: 660µW (typ.)
x Dual chip enables allow for depth expansion without
external logic
x IDT70V37 easily expands data bus width to 36 bits or
more using the Master/Slave select when cascading more
than one device

NOTES:
1. BUSY is an input as a Slave (M/S=VIL) and an output when it is a Master (M/S=VIH).
2. BUSY and INT are non-tri-state totem-pole outputs (push-pull).
