Technical specifications

Performance specifications as known at time of announcement

PC2100 DDR SDRAM -- The 2100 is derived from twice the front-side bus clock frequency (133 MHz x 2; data transfers can occur on both edges of the clock) times the module data width (64 bits / 8 bits/byte = 8 bytes) = 2,128, rounded = 2,100. This is the maximum data rate; the units are MBps.
Column Address Strobe (CAS) Latency (CL) of 2.5 (memory bus clock cycles)
Non-parity mode organized as 16M x 64, 32M x 64 and 64M x 64 respectively
Serial presence detect/decode
184-pin JEDEC/JEDIA standard UDIMM interface
Gold-plated leads
