IC41C4405x Datasheet
IC41C4405x and IC41LV4405x Series
4M x 4 (16-MBIT) DYNAMIC RAM
WITH FAST PAGE MODE
FEATURES
• Fast Page Mode Access Cycle
• TTL compatible inputs and outputs
• Refresh Interval:
-- 2,048 cycles/32 ms
-- 4,096 cycles/64 ms
• Refresh Mode: RAS-Only,
CAS-before-RAS (CBR), and Hidden
• JEDEC standard pinout
• Single power supply:
5V ± 10% or 3.3V ± 10%
• Byte Write and Byte Read operation via
two CAS
DESCRIPTION
The ICSI 4405x Series is a 4,194,304 x 4-bit high-performance
CMOS Dynamic Random Access Memory. The Fast Page
Mode allows 2,048 or 4096 random accesses within a single
row with access cycle time as short as 20 ns per 4-bit word.
These features make the 4405x Series ideally suited for high-
bandwidth graphics, digital signal processing, high-performance
computing systems, and peripheral applications.
The 4405x Series is packaged in a 24-pin 300mil SOJ and a 24
pin TSOP-2
