General Description
The HT23C020 is a read-only memory with
high performance CMOS storage device whose
2048K of memory is arranged into 262144
words by 8 bits.
For application flexibility, the chip enable and
output enable control pins can be selected as
active high or active low. This flexibility not
only allows easy interface with most microproc-
essors, but also eliminates bus contention in
multiple bus microprocessor systems. An addi-
tional feature of the HT23C020 is its ability to
enter the standby mode whenever the chip en-
able (CE /CE or CE 1/CE 1) is inactive, thus re-
ducing current consumption to below 30
μ
A. The
combination of these functions make the chip
suitable for high density low power memory
applications.
