TMS411616,384·81T DYNAMIC RANDOM·ACCESS MEMORYoperationaddress (AO through A6)Fourteen address bits are required to decode 1 of 16,384 storage cell locations. Seven row-address bits are set upon pins AO through A6 and latched onto the chip by the row-address strobe (RAS). Then the seven column-addressbits are set up on pins AO through A6 and latched onto the chip by the column-address trobe (CAS). <strong>Al</strong>l addressesmust be stable on or before the falling edges of RAS and CAS. RAS is similar to a chip enable in that it activatesthe sense amplifiers as well as the row decoder. CAS is used as a chip select activating the column decoder and theinput and output buffers.write enable(W)The read or write mode is selected through the write enable (W) input. A logic high on the W input selects the readmode and a logic low selects the write mode. The write enable terminal can be driven from standard TTL circuitswithout a pull-up resistor. The data input is disabled when the read mode is selected. When W goes low prior to CAS,data-out will remain in the high-impedance state for the entire cycle permitting common 1/0 operation.c-
