preliminary Data Sheet
Rev.0.9 12.07.2013
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
EEPROM using the standard I2C 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.
