PIN FUNCTIONS
The device is a serial access memory which utilizes time-sharing input of address information.
Command Latch Enable: CLE
register. The command is latched into the command register from the I/O port on the rising edge of the WE
signal while CLE is High.
Address Latch Enable: ALE
information is latched into the address register from the I/O port on the rising edge of WE while ALE is High.
Chip Enable:
operation, and will not enter Standby mode even if the CE input goes High.
Write Enable:
Read Enable:
I/O Port: I/O1 to 8

Write Protect:
regulator is reset when WP is Low. This signal is usually used for protecting the data during the power-on/off
sequence when input signals are invalid.
Ready/Busy:

The CLE input signal is used to control loading of the operation mode command into the internal command
The ALE signal is used to control loading address information into the internal address register. Address

The WE signal is used to control the acquisition of data from the I/O port.
The RE signal controls serial data output. Data is available t
The internal column address counter is also incremented (Address = Address + l) on this falling edge.
