W332M64V-XSBX  
32Mx64 Synchronous DRAM  
FEATURES  
GENERAL DESCRIPTION  
 High Frequency = 100, 125, 133MHz  
The 256MByte (2Gb) SDRAM is a high-speed CMOS, dynamic  
random-access, memory using 4 chips containing 536,870,912  
bits. Each chip is internally configured as a quad-bank DRAM with  
a synchronous interface. Each of the chip’s 134,217,728-bit banks  
is organized as 8,192 rows by 1,024 columns by 16 bits.  
 Package:  
• 208 Plastic Ball Grid Array (PBGA), 13 x 22mm  
 3.3V ±0.3V power supply  
 Fully Synchronous; all signals registered on positive edge  
Read and write accesses to the SDRAM are burst oriented;  
accesses start at a selected location and continue for a  
programmed number of locations in a programmed sequence.  
Accesses begin with the registration of an ACTIVE command,  
which is then followed by a READ or WRITE command. The  
address bits registered coincident with the ACTIVE command  
are used to select the bank and row to be accessed (BA0, BA1  
select the bank;A0-12 select the row). The address bits registered  
coincident with the READ or WRITE command are used to select  
the starting column location for the burst access.  
of system clock cycle  
 Internal pipelined operation; column address can be  
changed every clock cycle  
 Internal banks for hiding row access/precharge  
 Programmable Burst length 1,2,4,8 or full page  
 8192 refresh cycles  
 Commercial, Industrial and Military Temperature Ranges  
 Organized as 32M x 64  
The SDRAM provides for programmable READ or WRITE burst  
lengths of 1, 2, 4 or 8 locations, or the full page, with a burst  
terminate option.AnAUTO PRECHARGE function may be enabled  
to provide a self-timed row precharge that is initiated at the end  
of the burst sequence.  
 Weight: W332M64V-XSBX - 1.4 grams typical  
BENEFITS  
 73% SPACE SAVINGS  
The 2Gb SDRAM uses an internal pipelined architecture to achieve  
high-speed operation. This architecture is compatible with the 2n rule  
of prefetch architectures, but it also allows the column address to  
be changed on every clock cycle to achieve a high-speed, fully  
random access. Precharging one bank while accessing one of  
the other three banks will hide the precharge cycles and provide  
seamless, high-speed, random-access operation.  
 Reduced part count  
 Reduced trace lengths for lower parasitic capacitance  
 Suitable for hi-reliability applications  
* This product is to change without notice.  
The 2Gb SDRAM is designed to operate at 3.3V. An auto refresh  
mode is provided, along with a power-saving, power-down mode.  
All inputs and outputs are LVTTL compatible. SDRAMs offer  
substantial advances in DRAM operating performance, including  
the ability to synchronously burst data at a high data rate with  
automatic column-address generation, the ability to interleave  
between internal banks in order to hide precharge time and the  
capability to randomly change column addresses on each clock  
cycle during a burst access.
