Description
IBM13N4644MCB / IBM13N4734MCB are unbuf-
fered 168-pin Synchronous DRAM Dual In-Line
Memory Modules (DIMMs) which are organized as
4Mx64 and 4Mx72 high-speed memory arrays. The
DIMMs use 4(4Mx64) or 5(4Mx72) 4Mx16 SDRAMs
in 400mil TSOP II packages. The DIMMs achieve
high-speed data transfer rates of up to 100MHz by
employing a prefetch/pipeline hybrid architecture
that supports the JEDEC 1N rule while allowing very
low burst power.
The -10 speed sort DIMMs comply with JEDEC
standards for 168-pin unbuffered SDRAM DIMMs.
The -360 speed sort DIMMs are compatible with the
Intel PC100 SDRAM unbuffered DIMM specification.
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, CK2). Internal oper-
ating modes are defined by combinations of RAS,
CAS, WE, S0/S2, DQMB, and CKE0 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.
