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 C AS 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 Taiwan Memory Technology, Inc. reserves the right P. 1 to change products or specifications without notice.
