Abstract:
1. A memory module buffer comprising: a host-side memory channel port and a memory device channel port; a command decoder to decode commands received at the host-side memory channel port, the commands including at least one implicit command type, wherein the at least one implicit command type includes at least one implicit write command with a command format that specifies a first region of memory to be written to and includes less explicit write data than would be needed to fill the region of memory, the buffer further comprising a write data generator to form implicit write data in accordance with the implicit write command and further wherein the at least one implicit write command includes a copy command specifying a second region of memory to be read from to form the implicit write data, the memory device access controller responding to the copy command by causing the buffer to read data from the second region of memory to form the implicit write data; and a memory device access controller to respond to a command having an implicit command type by generating at least one explicit memory access command to the memory device channel port.
