Technical Specifications
Performance Specifications as known at time of announcement:  

• PC2100 Double Data Rate (DDR) Synchronous DRAM (SDRAM). The '2100' is derived from twice the front side bus clock frequency (133MHz x 2; data transfers can occur on both edges of the clock) times the module data width (64 bits / 8 bits/byte = 8 bytes) = 2128, rounded = 2100. This is the maximum data rate, the units are MB/second.
• Non-parity mode organized as 16Mx64, 32Mx64, and 64Mx64 respecively.
• Serial presence detect/decode
• 200-pin JEDEC/JEDIA standard SODIMM interface
• Gold-plated leads
