IS41C16100S  
IS41LV16100S  
1M x 16 (16-MBIT) DYNAMIC RAM  
WITH EDO PAGE MODE  
DESCRIPTION  
FEATURES  
The ICSI IS41C16100S and IS41LV16100S are 1,048,576 x  
16-bit high-performance CMOS Dynamic Random Access  
Memories. These devices offer an accelerated cycle access  
called EDO Page Mode. EDO Page Mode allows 1,024 ran-  
dom accesses within a single row with access cycle time as  
short as 20 ns per 16-bit word. The Byte Write control, of upper  
and lower byte, makes the IS41C16100S ideal for use in  
16-, 32-bit wide data bus systems.  
• Extended Data-Out (EDO) Page Mode access cycle  
• TTL compatible inputs and outputs; tristate I/O  
• Refresh Interval:  
Refresh Mode: 1,024 cycles /16 ms  
RAS-Only, CAS-before-RAS (CBR), and Hidden  
Self refresh Mode - 1,024 cycles / 128ms  
• JEDEC standard pinout  
• Single power supply:  
These features make the IS41C16100Sand IS41LV16100S  
ideally suited for high-bandwidth graphics, digital signal  
processing, high-performance computing systems, and  
peripheral applications.  
5V ± 10% (IS41C16100S)  
3.3V ± 10% (IS41LV16100S)  
• Byte Write and Byte Read operation via two CAS  
• Industrail Temperature Range -40°C to 85°C  
The IS41C16100S and IS41LV16100S are packaged in a  
42-pin 400mil SOJ and 400mil 50- (44-) pin TSOP-2.
