US Patent 9916873 Extended capacity memory module with dynamic data buffers

A memory module uses dynamic data buffers for providing extended capacity for computing systems. The memory module comprises an external interface having a first set of data pins and a second set of data pins. The memory module includes a first set of memory chips and a second set of memory chips. The memory module includes a first registering clock driver to control the first set of memory chips and a second registering clock driver to control the second set of memory chips. The memory module further includes a first data buffer to connect the first set of memory chips to the first set of data pins and a second data buffer to connect the second set of memory chips to the second set of data pins.
