DESCRIPTION
The
ICSI
4105 Series is a 1,048,576 x 4-bit high-performance
CMOS Dynamic Random Access Memory. The Fast Page
Mode allows 1,024 random accesses within a single row with
access cycle time as short as 20 ns per 4-bit word.
These features make the 4105 Series ideally suited for digital
signal processing, and low power portable audio applications.
The 4105 Series is packaged in a 20-pin 300mil SOJ and a 20
pin TSOP-2
1M x 4 (4
MBIT) DYNAMIC RAM
WITH FAST PAGE MODE
