PIPELINED, SCD SYNCBURST SRAM
GENERAL DESCRIPTION (continued)
(CE2, CE2#), burst control inputs (ADSC#, ADSP#,
ADV#), byte write enables (BWx#), and global write
(GW#).
Asynchronous inputs include the output enable
(OE#), clock (CLK), and snooze enable (ZZ). There is
also a burst mode pin (MODE) that selects between
interleaved and linear burst modes. The data-out (Q),
enabled 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.
Burst operation can be initiated with either address
status processor (ADSP#) or address status controller
(ADSC#) input pins. Subsequent burst addresses can be
internally generated as controlled by the burst advance
pin (ADV#).
Address and write control are registered on-chip to
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;
BWb# controls DQb pins and DQPb; BWc# controls
DQc pins and DQPc; BWd# controls DQd pins and
DQPd. GW# LOW causes all bytes to be written. Parity
pins are only available on the x18 and x36 versions.
This device incorporates a single-cycle deselect fea-
ture during READ cycles. If the device is immediately
deselected after a READ cycle, the output bus goes to a
High-Z state
t
KQHZ nanoseconds after the rising edge
of clock.
Micron’s 2Mb SyncBurst SRAMs operate from a
+3.3V V
DD
power supply, and all inputs and outputs
are 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.
