PD46364365B
36M-BIT DDR II SRAM SEPARATE I/O
2-WORD BURST OPERATION
Description
The
μ
PD46364185B is a 2,097,152-word by 18-bit and the
μ
PD46364365B is a 1,048,576-word by 36-bit synchronous
double data rate static RAM fabricated with advanced CMOS technology using full CMOS six-transistor memory cell.
The
μ
PD46364185B and
μ
PD46364365B integrate unique synchronous peripheral circuitry and a burst counter. All input
registers controlled by an input clock pair (K and K#) are latched on the positive edge of K and K#.
These products are suitable for application which require synchronous operation, high speed, low voltage, high density and
wide bit configuration. These products are packaged in 165-pin PLASTIC BGA.

Pin Description

Symbol

Type
Input
Description
Synchronous Address Inputs: These inputs are registered and must meet the setup and hold
times around the rising edge of K. All transactions operate on a burst of two words (one
clock period of bus activity). These inputs are ignored when device is deselected, i.e., NOP
(LD# = HIGH).
Synchronous Data Inputs: Input data must meet setup and hold times around the rising
edges of K and K# during WRITE operations. See
Pin Arrangement
for ball site location of
individual signals.
x18 device uses D0 to D17.
x36 device uses D0 to D35.
Synchronous Data Outputs: Output data is synchronized to the respective C and C# or to K
and K# rising edges if C and C# are tied HIGH. Data is output in synchronization with C and
C# (or K and K#), depending on the LD# and R, W# command. See
Pin Arrangement
for
ball site location of individual signals.
x18 device uses Q0 to Q17.
x36 device uses Q0 to Q35.
Synchronous Load: This input is brought LOW when a bus cycle sequence is to be defined.
This definition includes address and read/write direction. All transactions operate on a burst
of 2 data (one clock period of bus activity).
Synchronous Read/Write Input: When LD# is LOW, this input designates the access type
(READ when R, W# is HIGH, WRITE when R, W# is LOW) for the loaded address. R, W#
must meet the setup and hold times around the rising edge of K.
Synchronous Byte Writes: When LOW these inputs cause their respective byte to be
registered and written during WRITE cycles. These signals must meet setup and hold times
around the rising edges of K and K# for each of the two rising edges comprising the WRITE
cycle. See
Pin Arrangement
for signal to data relationships.
x18 device uses BW0#, BW1#.
x36 device uses BW0# to BW3#.
See
Byte Write Operation
for relation between BWx# and Dxx.
Input Clock: This input clock pair registers address and control inputs on the rising edge of
K, and registers data on the rising edge of K and the rising edge of K#. K# is ideally 180
degrees out of phase with K. All synchronous inputs must meet setup and hold times around
the clock rising edges.
Output Clock: This clock pair provides a user controlled means of tuning device output data.
The rising edge of C# is used as the output timing reference for first output data. The rising
edge of C is used as the output reference for second output data. Ideally, #C is 180 degrees
out of phase with C. When use of K and K# as the reference instead of C and C#, then fixed
C and C# to HIGH. Operation cannot be guaranteed unless C and C# are fixed to HIGH
(i.e. toggle of C and C#)
