BUFFER COMMUNICATION FOR DATA BUFFERS SUPPORTING MULTIPLE PSEUDO CHANNELS

Abstract:

A memory module has data buffers coupled to a registered clock driver (RCD) via buffer communication (BCOM) bus. The memory module includes memory devices managed as a first pseudo channel and a second pseudo channel. The data buffers manage data transmission between the memory devices and a host based on commands received over the BCOM bus. The RCD can send a first BCOM command on the BCOM bus to the data buffer, the first BCOM command to specify a rank and a burst length for the first pseudo channel. The RCD can send a second BCOM command on the BCOM bus to the data buffer, the second BCOM command to specify a rank and a burst length for the second pseudo channel, and a timing offset relative to the first BCOM command.
