Description  
The IBM0325404CT3, IBM0325804CT3, and  
IBM0325164CT3 are four-bank Synchronous  
address data in the conventional RAS/CAS multi-  
plexing style. Thirteen row addresses (A0-A12) and  
two bank select addresses (BA0, BA1) are strobed  
with RAS. Eleven column addresses (A0-A9, A11)  
plus bank select addresses and A10 are strobed  
with CAS. Column address A11 is dropped on the  
x8 device, and column addresses A11 and A9 are  
dropped on the x16 device.  
DRAMs organized as 16Mbit x 4 I/O x 4 Bank, 8Mbit  
x 8 I/O x 4 Bank, and 4Mbit x 16 I/O x 4 Bank,  
respectively. These synchronous devices achieve  
high-speed data transfer rates of up to 133MHz by  
employing a pipeline chip architecture that synchro-  
nizes the output data to a system clock. The chip is  
fabricated with IBM’s advanced 256Mbit single tran-  
sistor CMOS DRAM process technology.  
Prior to any access operation, the CAS latency,  
burst length, and burst sequence must be pro-  
grammed into the device by address inputs A0-A12,  
BA0, BA1 during a mode register set cycle. In addi-  
tion, it is possible to program a multiple burst  
sequence with single write cycle for write through  
cache operation.  
The device is designed to comply with all JEDEC  
standards set for synchronous DRAM products,  
both electrically and mechanically. All of the control,  
address, and data input/output (I/O or DQ) circuits  
are synchronized with the positive edge of an exter-  
nally supplied clock.  
Operating the four memory banks in an interleave  
fashion allows random access operation to occur at  
a higher rate than is possible with standard DRAMs.  
A sequential and gapless data rate of up to 133MHz  
is possible depending on burst length, CAS latency,  
and speed grade of the device. Auto Refresh (CBR)  
and Self Refresh operation are supported.  
RAS, CAS, WE, and CS are pulsed signals which  
are examined at the positive edge of each externally  
applied clock (CK). Internal chip operating modes  
are defined by combinations of these signals and a  
command decoder initiates the necessary timings  
for each operation. A fifteen bit address bus accepts
