Abstract
Provided are a method and apparatus for method and apparatus for encoding registers in a memory module. A mode register command is sent to the memory module over a bus, initialization of the memory module before the bus to the memory module is trained for bus operations, to program one of a plurality of mode registers in the memory module, wherein the mode register command indicates one of the mode registers and includes data for the indicated mode register
Claims20
An apparatus, comprising:
- host memory controller logic to:
- send a mode register command to a memory module over a bus, during initialization of the memory module before the bus to the memory module is trained for bus operations, to program one of a plurality of mode registers in the memory module, wherein the mode register command indicates one of the mode registers and includes data for the indicated mode register.
A apparatus for a memory module, comprising:
- mode registers;
- memory chips to store data from a host memory controller;
- and
- memory module controller logic to:
- receive a mode register command from a host memory controller over a bus, during initialization of the memory module before the bus to the memory module is trained for bus operations, to program one of the mode registers, wherein the mode register command indicates one of the mode registers and includes data for the indicated mode register;
- and
- write the data included in the mode register command to the indicated mode register in the memory module controller.
