General Description

The Micron

Zero Bus Turnaround

™

(ZBT

) SRAM

family employs high-speed, low-power CMOS designs

using an advanced CMOS process.

Micron’s 18Mb ZBT SRAMs integrate a 1 Meg x 18,

512K x 32, or 512K x 36 SRAM core with advanced syn-

chronous peripheral circuitry and a 2-bit burst

counter. These SRAMs are optimized for 100 percent

bus utilization, eliminating any turnaround cycles for

READ to WRITE, or WRITE to READ, transitions. All

synchronous inputs pass through registers controlled

by a positive-edge-triggered single clock input (CLK).

The synchronous inputs include all addresses, all data

inputs, chip enable (CE#), two additional chip enables

ADV/LD#

TQFP Pin Descriptions

TYPE

Input

DESCRIPTION

Synchronous Address Advance/Load: When HIGH, this input is used to advance the internal

burst counter, controlling burst access after the external address is loaded. When ADV/LD# is

HIGH, R/W# is ignored. A LOW on ADV/LD# clocks a new address at the CLK rising edge.

Synchronous Byte Write Enables: These active LOW inputs allow individual bytes to be

written when a WRITE cycle is active and must meet the setup and hold times around the

rising edge of CLK. BWs need to be asserted on the same cycle as the address. BWs are

associated with addresses and apply to subsequent data. BWa# controls DQa pins; BWb#

controls DQb pins; BWc# controls DQc pins; BWd# controls DQd pins.

Synchronous Chip Enable: This active LOW input is used to enable the device and is sampled

only when a new external address is loaded (ADV/LD# LOW).

Synchronous Chip Enable: This active LOW input is used to enable the device and is sampled

only when a new external address is loaded (ADV/LD# LOW). This input can be used for

memory depth expansion.

Synchronous Chip Enable: This active HIGH input is used to enable the device and is sampled

only when a new external address is loaded (ADV/LD# LOW). This input can be used for

memory depth expansion.

Synchronous Clock Enable: This active LOW input permits CLK to propagate throughout the

device. When CKE is HIGH, the device ignores the CLK input and effectively internally

extends the previous CLK cycle. This input must meet setup and hold times around the rising

edge of CLK.

Clock: This signal registers the address, data, chip enables, byte write enables, and burst

control inputs on its rising edge. All synchronous inputs must meet setup and hold times

around the clock’s rising edge.

Mode: This input selects the burst sequence. A LOW on this pin selects linear burst. NC or

HIGH on this pin selects interleaved burst. Do not alter input state while device is operating.

LBO# is the JEDEC-standard term for MODE.

Output Enable: This active LOW, asynchronous input enables the data I/O output drivers. G#

is the JEDEC-standard term for OE#.

Read/Write: This input determines the cycle type when ADV/LD# is LOW and is the only

means for determining READs and WRITEs. READ cycles may not be converted into WRITEs

(and vice versa) other than by loading a new address. A LOW on this pin permits BYTE WRITE

operations and must meet the setup and hold times around the rising edge of CLK. Full bus-

width WRITEs occur if all byte write enables are LOW.

Synchronous Address Inputs: These inputs are registered and must meet the setup and hold

times around the rising edge of CLK. SA0 and SA1 are the two least significant bits (LSB) of

the address field and set the internal burst counter if burst is desired.

Snooze Enable: This active HIGH, asynchronous input causes the device to enter a low-power

standby mode in which all data in the memory array is retained. When ZZ is active, all other

inputs are ignored. This pin has an internal pull-down and can be left unconnected.

SRAM Data I/Os: Byte “a” is associated with DQa pins; byte “b” is associated with DQb pins;

byte “c” is associated with DQc pins; byte “d” is associated with DQd pins. Input data must

meet setup and hold times around the rising edge CLK.

No Function/Parity Data I/Os: On the x32 version, these are No Function (NF). On the x18

version, byte “a” parity is DQPa; byte “b” parity is DQPb. On the x36 version, byte “a” parity

is DQPa; byte “b” parity is DQPb; byte “c” parity is DQPc; byte “d” parity is DQPd.

Power Supply: See DC Electrical Characteristics and Operating Conditions for range.

Isolated Output Buffer Supply: See DC Electrical Characteristics and Operating Conditions for

range.

Ground: GND.
