IS41C16105  
IS41LV16105  
1M x 16 (16-MBIT) DYNAMIC RAM  
WITH FAST PAGE MODE  
DESCRIPTION  
FEATURES  
The ICSI IS41C16105 and IS41LV16105 are 1,048,576 x  
16-bit high-performance CMOS Dynamic Random Access  
Memories. Fast Page Mode allows 1,024 random 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 IS41C16105 ideal for use in 16-, 32-bit wide data  
bus systems.  
• TTL compatible inputs and outputs; tristate I/O  
• Refresh Interval: 1,024 cycles/16 ms  
• Refresh Mode: RAS-Only, CAS-before-RAS (CBR),  
Hidden  
• JEDEC standard pinout  
• Single power supply:  
5V ± 10% (IS41C16105)  
3.3V ± 10% (IS41LV16105)  
These features make the IS41C16105 and IS41LV16105  
ideally suited for high-bandwidth graphics, digital signal  
processing, high-performance computing systems, and  
peripheral applications.  
• Byte Write and Byte Read operation via two CAS  
• Industrail temperature range -40oC to 85oC  
The IS41C16105 and IS41LV16105 are packaged in a  
42-pin 400mil SOJ and 400mil 44- (50-) pin TSOP-2.
