buffer type for a multi - rank dual inline ' memory modules or more rank - double rows connection - memory module (dimm)

摘要

Buffer chip for the drive of external input signals, on which a large amount of compartment rank - double rows of memory module (mr - dimm) are applied to a predetermined number (n) of memory chips, which on a printed circuit board, of the double rows of memory module are fastened,the buffer has chip:the stacked register substrates, wherein each of a few signal driver has, wherein at least two signal drivers are connected in parallel, in order to an external input signal to drive to the memory chip.
