GENERAL DESCRIPTION
The T221160A is a randomly accessed solid state
memory containing 1,048,551 bits organized in a
x16 configuration. The T221160A has both BYTE
WRITE and WORD WRITE access cycles via two
CAS pins. It offers Fast Page mode operation
The T221160A CAS function and timing are
determined by the first CAS to transition low and
by the last to transition back high. Use only one of
the two CAS and leave the other staying high
during WRITE will result in a BYTE WRITE.
CASL transiting low in a WRITE cycle will write
data into the lower byte (IO1~IO8), and CASH
transiting low will write data into the upper byte
(IO9~16).
