256MB, 512MB, 1GB Registered DIMM
Rev. 1.4 May 2004
SDRAM
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. D
IN
is to be issued 1clock after write command in external timing because D
IN
is issued directly to module.
