Minimum address setup and hold time requirements must be met. After the required hold time, the addresses may change state without affecting device operation. During time (T = 1) the data output becomes enabled; however, the data is not valid until during time (T = 2). W must remain high for the read cycle. After the output data has been read, E may return high (T = 3). This will disable the chip and force the output buffer to a high impedance state. After the required E high time (TEHEL) the RAM is ready for the next memory cycle (T = 4).

The write portion of the cycle is defined as both E and W being low simultaneously. W may go low anytime during the cycle, provided that the write enable pulse setup time (TWLEH) is met. The write portion of the cycle is terminated by the first rising edge of either E or W. Data setup and hold times must be referenced to the terminating signal. If a series of consecutive write cycles are to be performed, the W line may remain low until all desired locations have been written. When this method is used, data setup and hold times must be referenced to the rising edge of E. By positioning the W pulse at different times within the E low time (TELEH), various types of write cycles may be performed. If the E low time (TELEH) is greater than the W pulse (TWLWH), plus an output enable time (TELQX), a combination read write cycle is executed. Data may be modified an indefinite number of times during any write cycle (TELEH). The data input and data output pins may be tied together for use with a common I/O data bus structure. When using the RAM in this method, allow a minimum of one output disable time (TWLQZ) after W goes low before applying input data to the bus. This will ensure that the output buffers are not active.
