Description
IBM13N16644HCB / IBM13N16734HCB are unbuf-
fered 168-pin Synchronous DRAM Dual In-Line
Memory Modules (DIMMs) which are organized as
16Mx64 and 16Mx72 high-speed memory arrays
and are configured as two 8M x 64/72 physical
tanks. The DIMMs use sixteen (16Mx64) or eigh-
teen(16Mx72) 8Mx8 SDRAMs in 400mil TSOP II
packages. The DIMMs achieve high-speed data-
transfer rates of up to 133MHz by employing a
prefetch/pipeline hybrid architecture that supports
the JEDEC 1N rule while allowing very low burst
power.
All control, address, and data input/output circuits
are synchronized with the positive edge of the exter-
nally supplied clock inputs.
All inputs are sampled at the positive edge of each
externally supplied clock (CK0 - CK3). Internal oper-
ating modes are defined by combinations of RAS,
CAS, WE, S0-S3, DQMB, and CKE0-CKE1 signals.
A command decoder initiates the necessary timings
for each operation. A 14-bit address bus accepts
address information in a row/column multiplexing
arrangement.
Prior to any Access operation, the CAS latency,
burst type, burst length, and burst operation type
must be programmed into the DIMM by address
inputs A0-A9 during the Mode Register Set cycle.
The DIMM uses serial presence detects imple-
mented via a serial EEPROM using the two pin IIC
protocol. The first 128 bytes of serial PD data are
used by the DIMM manufacturer. The last 128 bytes
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 both EDO DRAM
and SDRAM unbuffered DIMMs in both non-parity
x64 and ECC-Optimized x72 configurations.
