Description

IBM11N1645L/IBM11N1735Q industry standard

168-pin 8-byte Dual In-line Memory Modules

(DIMMs) which are organized as 1Mx64 and 1Mx72

high speed memory arrays designed with EDO

DRAMs for non-parity or ECC applications. The x64

DIMM uses 4 1Mx16 EDO DRAMs (TSOP or SOJ)

and the x72 DIMM uses 4 1Mx16 plus 2 1Mx4 EDO

DRAMs (all in SOJ packages). The use of EDO

DRAMs allows for a reduction in Page Mode Cycle

time from 40ns (Fast Page) to 25ns for 60ns DRAM

modules.

(SCL) and Data I/O (SDA) lines to synchronously

clock data between the master (system logic) and

the slave EEPROM device (DIMM). The EEPROM

device address pins (SA0-2) are brought out to the

DIMM tabs to allow 8 unique DIMM/EEPROM

addresses. The first 128 bytes are utilized by the

DIMM manufacturer and the second 128 bytes of

serial PD data are available to the customer.

All IBM 168-pin DIMMs provide a high performance,

flexible 8-byte interface in a 5.25” long space-saving

footprint. Related products include the unbuffered

X72 ECC DIMMs and the buffered DIMMs (x64, x72

parity and x72 ECC Optmized) for applications

which can benefit from the on-card buffers.

The DIMMs use serial presence detects imple-

mented via a serial EEPROM using the two pin I C

protocol. This communication protocol uses Clock
