NOTE: 1. Device selected only if both S1 and S2 are low, and deselected if either S1 or S2 are high.
In the HM-6518/883 read cycle the address information is
latched into the on chip registers on the falling edge of E
(T = 0). Minimum address setup and hold time requirements must be met. After the required hold time the
addresses may change state without affecting device operation. In order for the output to be read S1, S2 and E must
be low, W must be high. When E goes high the output data
is latched into an on chip register. Taking either or both S1
or S2 high, forces the output buffer to a high impedance
state. The output data may be re-enabled at any time by
taking S1 and S2 low. On the falling edge of E the data will
be unlatched.

FUNCTION
NOTE: 1. Device selected only if both S1 and S2 are low, and deselected if either S1 or S2 are high.
The write cycle is initiated by the falling edge of E which
latches the address information into the on chip registers.
The write portion of the cycle is defined as E, W, S1 and S2
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, W, S1 or S2. 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 (TSLQX), 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.
