GENERAL DESCRIPTION
The Austin Semiconductor, Inc. AS4C4M4DG is a
4,194,304 x 4 bit Fast Page Mode CMOS DRAM offering
high speed random access of memory cells within the same
row. This device features a +5V (±10%) power supply,
refresh cycle (2K), and fast access times (60 and 70ns). Other
features include CAS\-before-RAS\, RAS\-only refresh, self-
refresh operation (128ms refresh period), and Hidden refresh
capabilities. This 4M x 4 Fast Page Mode DRAM is
fabricated using an advanced CMOS process to realize high
bandwidth, low power consumption and high reliability. It may
be used as main memory for high level computers, micro-
computers and personal computers.
