1Mx16 Single Transistor RAM
1M x16 bit Single Transistor RAM
GENERAL DESCRIPTION
The EM7164SU16 is 16,777,216 bits of Single Transistor RAM which uses DRAM type memory cells, but
this device has refresh-free operation and extreme low power consumption technology. Furthermore the
interface is compatible to a low power Asynchronous type SRAM. The EM7164SU16 is organized as
1,048,576 Words x 16 bit.
FEATURES
- Organization :1M x16

NOTES (WRITE CYCLE)
1. A write occurs during the overlap(tWP) of low CS, low WE and low UB or LB. A write begins at the last transition
among low CS and low WE with asserting UB or LB low for single byte operation or simultaneously asserting
UB and LB low for word operation. A write ends at the earliest transition among high CS and high WE.
The tWP is measured from the beginning of write to the end of write.
2. tCW is measured from CS going low to end od write.
3. tAS is measured from the address valid to the beginning of write.
4. tWR is measured from the end of write to the address change. tWR applied in case a write ends as CS or WE
going high.
5. Do not Access device with cycle timing shorter than tWC for continuous periods > 40us.
