DRAM Modules - DDR1

DDR Double Data Rate SDRAM (also known as DDR1 or just DDR) is the successor technology of the Single Data Rate SDRAM. In comparison to previous SDRAM technologies, a significantly higher data transfer is achieved by transmitting data on both edges (rise and fall) of the synchronous strobe signal.

Intelligent Memory's portfolio covers densities of up to 1GB.  For this technology, we offer special modules based on components with embedded ECC functionality. These modules turn a non-ECC module (64Bit wide data bus) into a device with the reliability of a typical ECC module.
DDR1 Modules
DIMM Type Form Factor Capacity Maximum Speed Temperature* Height Component Data Width
Non-ECC UDIMM 184pin DIMM 1GB, 512MB PC-3200 (400MT/s) Commercial, Industrial 1.16" x8
Non-ECC SODIMM 200pin SODIMM 1GB, 512MB, 256MB PC-3200 (400MT/s) Commercial, Industrial 1.25" x8, x16

*Commercial = 0°C to +95°C  /  Industrial = -40°C to +95°C  /  High = -40°C to +105°C
