Description

IBM11N8645H/IBM11N8735H are industry standard

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

(DIMMs) which are organized as 8Mx64 and 8Mx72

high speed memory arrays designed with EDO

DRAMs for non-parity or ECC applications. The

DIMMs use 8 (x64) or 9 (x72) 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 20ns for 50ns DRAM modules.

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 buffered

DIMMs (x64 non- parity and x72 ECC Optmized) for

applications which can benefit from the on-card buff-

ers.

The DIMMs use serial presence detects imple-

mented via a serial EEPROM using the two-pin IIC

protocol. This communication protocol uses Clock

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