*Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

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
