GENERAL DESCRIPTION
The T224160B is a randomly accessed solid state
memory containing 4,194,304 bits organized in a x16
configuration. The T224160B has both BYTE
WRITE and WORD WRITE access cycles via two
CAS pins. It offers Fast Page mode operation
The T224160B 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).
