This Swissbit module is an industry standard 200-pin 8-byte DDR2 SDRAM Small Outline Dual-In-line Memory
Module (SO-DIMM) which is organized as x64 high speed CMOS memory arrays. The module uses internally
configured octal-bank DDR2 SDRAM devices. The module uses double data rate architecture to achieve high-
speed operation. DDR2 SDRAM modules operate from a differential clock (CK and CK#). READ and WRITE
accesses to a DDR2 SDRAM module is burst-oriented; accesses start at a selected location and continue for a
programmed number of locations in a programmed sequence. The burst length is either four or eight locations. An
auto precharge function can be enabled to provide a self-timed row precharge that is initiated at the end of a burst
access. The DDR2 SDRAM devices have a multibank architecture which allows a concurrent operation that is
providing a high effective bandwidth. A self refresh mode is provided and a power-saving “power-down” mode. All
inputs and all full drive-strength outputs are SSTL_18 compatible.
The DDR2 SDRAM module uses the optional serial presence detect (SPD) function implemented via serial
2
EEPROM using the standard I C protocol. This nonvolatile storage device contains 256 bytes. The first 128 bytes
are utilized by the SO-DIMM manufacturer (Swissbit) to identify the module type, the module’s organization and
several timing parameters. The second 128 bytes are available to the end user.
