(OE#), clock (CLK) and snooze enable (ZZ). There is also
a burst mode input (MODE) that selects between inter-
leaved and linear burst modes. The data-out (Q), en-
abled by OE#, is also asynchronous. WRITE cycles can
be from one to two bytes wide (x18) or from one to four
bytes wide (x32/x36), as controlled by the write control
inputs.
status processor (ADSP#) or address status controller
(ADSC#) inputs. Subsequent burst addresses can be
internally generated as controlled by the burst advance
input (ADV#).
simplify WRITE cycles. This allows self-timed WRITE
cycles. Individual byte enables allow individual bytes
to be written. During WRITE cycles on the x18 device,
BWa# controls DQa pins and DQPa; BWb# controls
DQb pins and DQPb. During WRITE cycles on the x32
and x36 devices, BWa# controls DQa pins and DQPa;

TTL-compatible. Users can choose either a 3.3V or 2.5V
I/O version. The device is ideally suited for Pentium
and PowerPC pipelined systems and systems that ben-
efit from a very wide, high-speed data bus. The device
is also ideal in generic 16-, 18-, 32-, 36-, 64-, and 72-bit-
wide applications.
