IS61QDB42M18A

IS61QDB41M36A

2Mx18, 1Mx36

36Mb QUAD (Burst 4) SYNCHRONOUS SRAM

JANUARY 2014

FEATURES

DESCRIPTION

The 36Mb IS61QDB41M36A and IS61QDB42M18A are

synchronous, high-performance CMOS static random access

memory (SRAM) devices. These SRAMs have separate I/Os,

eliminating the need for high-speed bus turnaround. The

rising edge of K clock initiates the read/write operation, and

all internal operations are self-timed. Refer to the Timing

Reference Diagram for Truth Table for a description of the

basic operations of these QUAD (Burst of 4) SRAMs.



1Mx36 and 2Mx18 configuration available.

On-chip Delay-Locked Loop (DLL) for wide data

valid window.



Separate independent read and write ports with

concurrent read and write operations.



Synchronous pipeline read with late write operation.

Double Data Rate (DDR) interface for read and

write input ports.

Read and write addresses are registered on alternating rising

edges of the K clock. Reads and writes are performed in

double data rate. The following are registered internally on

the rising edge of the K clock:



1.5 cycle read latency.

Fixed 4-bit burst for read and write operations.

Clock stop support.



Read/write address

Two input clocks (K and K#) for address and control

registering at rising edges only.

Read enable



Two output clocks (C and C#) for data output control.

Write enable

Two echo clocks (CQ and CQ#) that are delivered

simultaneously with data.

Byte writes for burst addresses 1 and 3

Data-in for burst addresses 1 and 3



+1.8V core power supply and 1.5, 1.8V VDDQ, used

with 0.75, 0.9V VREF.

The following are registered on the rising edge of the K#

clock:



HSTL input and output levels.



Byte writes for burst addresses 2 and 4

Registered addresses, write and read controls, byte

writes, data in, and data outputs.



Data-in for burst addresses 2 and 4



Full data coherency.

Byte writes can change with the corresponding data-in to

enable or disable writes on a per-byte basis. An internal write

buffer enables the data-ins to be registered one cycle after

the write address. The first data-in burst is clocked one cycle

later than the write command signal, and the second burst is

timed to the following rising edge of the K# clock. Two full

clock cycles are required to complete a write operation.

Boundary scan using limited set of JTAG 1149.1

functions.



Byte write capability.

Fine ball grid array (FBGA) package:

13mmx15mm and 15mmx17mm body size

165-ball (11 x 15) array



Programmable impedance output drivers via 5x

user-supplied precision resistor.

During the burst read operation, the data-outs from the first

and third bursts are updated from output registers of the

second and third rising edges of the C# clock (starting 1.5

cycles later after read command). The data-outs from the

second and fourth bursts are updated with the third and

fourth rising edges of the C clock. The K and K# clocks are

used to time the data-outs whenever the C and C# clocks are

tied high. Two full clock cycles are required to complete a

read operation.

The device is operated with a single +1.8V power supply and

is compatible with HSTL I/O interfaces.
