IS41LV4100
1Meg x 4 (4-MBIT) DYNAMIC RAM
WITH EDO PAGE MODE
ISSI®
www.DataSheet4U.com
PRELIMINARY INFORMATION
SEPTEMBER 2001
FEATURES
• TTL compatible inputs and outputs
• Refresh Interval: 1024 cycles/16 ms
• Refresh Mode : RAS-Only, CAS-before-RAS
(CBR), and Hidden
• JEDEC standard pinout
• Single power supply
5V ± 10% (IS41C4100)
3.3V ± 10% (IS41LV4100)
• Industrail Temperature Range -40oC to 85oC
DESCRIPTION
The ISSI IS41C4100 and IS41LV4100 are 1,048,576 x 4-bit
high-performance CMOS Dynamic Random Access
Memory. Both products offer accelerated cycle access
EDO Page Mode. EDO Page Mode allows 512 random
accesses within a single row with access cycle time as
short as 10ns per 4-bit word.
These features make the IS41C4100 and IS41LV4100 ideally
suited for high band-width graphics, digital signal processing,
high-performance computing systems, and peripheral applications.
The IS41C4100 and IS41LV4100 are available in a 20-pin,
300-mil SOJ package.

Note:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent
damage to the device. This is a stress rating only and functional operation of the device at these
or any other conditions above those indicated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions for extended periods may affect
reliability.
