Description
The GM72V66841ET/ELT is a synchronous
dynamic random access memory comprised of
67,108,864 memory cells and logic including
input and output circuits operating synchronously
by referring to the positive edge of the externally
provided Clock.
The GM72V66841ET/ELT provides four banks
of 2,097,152 word by 8 bit to realize high
bandwidth with the Clock frequency up to 143
Mhz.
Features
* PC133/PC100/PC66 Compatible
-7(143MHz)/-75(133MHz)/-8(125MHz)
-7K(PC100,2-2-2)/-7J(PC100,3-2-2)
* 3.3V single Power supply
* LVTTL interface
* Max Clock frequency
143/133/125/100MHz
* 4,096 refresh cycle per 64 ms
* Two kinds of refresh operation
Auto refresh / Self refresh
* Programmable burst access capability ;
- Sequence:Sequential / Interleave
- Length :1/2/4/8/FP
* Programmable CAS latency : 2/3
* 4 Banks can operate independently or
simultaneously
* Burst read/burst write or burst read/single
write operation capability
* Input and output masking by DQM input
* One Clock of back to back read or write
command interval
* Synchronous Power down and Clock
suspend capability with one Clock latency
for both entry and exit
* JEDEC Standard 54Pin 400mil TSOP II
