Rev. 0.1. Sept. 2001
PC133/PC100 Low Profile Registered DIMM
td, tr = Delay of register
Notes : 1. In case of module timing, command cycles delayed 1CLK with respect to external input timing at the address and input signal
because of the buffering in register. Therefore, Input/Output signals of read/write function should be issued 1CLK earlier as
compared to Unbuffered DIMMs.
2. DIN is to be issued 1clock after write command in external timing because DIN is issued directly to module.
