CY62137VN MoBL®
2-Mbit (128K x 16) Static RAM
portable applications such as cellular telephones. The device
also has an automatic power-down feature that reduces power
consumption by 99% when addresses are not toggling. The
device can also be put into standby mode when deselected
(CE HIGH) or when CE is LOW and both BLE and BHE are
HIGH. The input/output pins (I/O0 through I/O15) are placed in
a high-impedance state when: deselected (CE HIGH), outputs
are disabled (OE HIGH), BHE and BLE are disabled (BHE,
BLE HIGH), or during a write operation (CE LOW, and WE
LOW).Writing to the device is accomplished by taking Chip
Enable (CE) and Write Enable (WE) inputs LOW. If Byte Low
Enable (BLE) is LOW, then data from I/O pins (I/O0 through
I/O7), is written into the location specified on the address pins
(A0 through A16). If Byte High Enable (BHE) is LOW, then data
from I/O pins (I/O8 through I/O15) is written into the location
specified on the address pins (A0 through A16).Reading from
the device is accomplished by taking Chip Enable (CE) and
Output Enable (OE) LOW while forcing the Write Enable (WE)
HIGH. If Byte Low Enable (BLE) is LOW, then data from the
memory location specified by the address pins will appear on
I/O0 to I/O7. If Byte High Enable (BHE) is LOW, then data from
memory will appear on I/O8 to I/O15. See the truth table at the
back of this data sheet for a complete description of read and
write modes.

9. If both byte enables are toggled together this value is 10 ns.
10. The internal write time of the memory is defined by the overlap of CE LOW and WE LOW. Both signals must be LOW to initiate a write and either signal can
terminate a write by going HIGH. The data input set-up and hold timing should be referenced to the rising edge of the signal that terminates the write.
11. The minimum write cycle time for write cycle #3 (WE controlled, OE LOW) is the sum of t
