Description  
IBM11T8645HP is an industry standard 144-pin  
8-byte Small Outline Dual In-line Memory Module  
(SO DIMM) which is organized as an 8Mx64 high  
speed memory array designed for use in non-parity  
applications. The SO DIMM uses 8 8Mx8 EDO  
DRAMs in TSOP packages. The use of EDO  
DRAMs allows for a reduction in Page Mode Cycle  
time from 40ns (Fast Page) to 15ns for 60ns EDO  
modules.  
chronously clock data between the master (for  
example, the System Microprocessor) and the slave  
EEPROM device. The device address for the  
EEPROM is set to zero at the card. The first 128  
bytes are utilized by the SO DIMM manufacturer,  
and the second 128 bytes are available to the end  
user.  
All IBM 144-pin SO DIMMs provide a high perfor-  
mance, flexible 8-byte interface in a 2.66" long  
space-saving footprint. Related products are the  
1Mx64, 2Mx64, 4Mx64 and the x72 (ECC) SO  
DIMMs.  
This card uses Serial Presence Detects (SPDs)  
implemented via a serial EEPROM using the two pin  
2
I C Protocol. This communication protocol uses  
CLOCK (SCL) and DATA I/O (SDA) lines to syn-
