DESCRIPTION

The HY628400A is a high-speed, low power and
4M bits CMOS SRAM organized as 512K words
by 8 bits. The HY628400A uses Hynix's high
performance twin tub CMOS process technology
and was designed for high-speed and low power
circuit technology. It is particularly well suited for
use in high-density and low power system
applications. This device has a data retention
mode that guarantees data to remain valid at the
minimum power supply voltage of 2.0V.

FEATURES

Notes:
1. A write occurs during the overlap of a low /WE and a low /CS.
2. tWR is measured from the earlier of /CS or /WE going high to the end of write cycle.
3. During this period, I/O pins are in the output state so that the input signals of opposite phase to the
output must not be applied.
4. If the /CS low transition occur simultaneously with the /WE low transition or after the
/WE transition, outputs remain in a high impedance state.
5. Q(data out) is the same phase with the write data of this write cycle.
6. Q(data out) is the read data of the next address.
7. Transition is measured + 200mV from steady state.
This parameter is sampled and not 100% tested.
