Abstract
Apparatuses, hybrid memory modules, memories, and methods for configuring I/Os of a memory for a hybrid memory module are described. An example apparatus includes a non-volatile memory, a control circuit coupled to the non-volatile memory, and a volatile memory coupled to the control circuit. The volatile memory is configured to enable a first subset of I/Os for communication with a bus and enable a second subset of I/O for communication with the control circuit, wherein the control circuit is configured to transfer information between the volatile memory and the non-volatile memory.
Claims20
A method, comprising:
- receiving, at a memory module from a host, a command to perform a save operation, wherein the save operation includes saving data of a volatile memory of the memory module to a non-volatile memory (NVM) of the memory module;
- in response to the command, programming, by the memory module, a mode register of the volatile memory with information that configures the volatile memory to enable transfer of the data from the volatile memory to the NVM.
An apparatus, comprising:
- a volatile memory;
- a non-volatile memory (NVM);
- a control circuit coupled between the NVM and the volatile memory and configured to facilitate a save operation to cause transfer of data from the volatile memory to the NVM in response to a command to perform the save operation;
- and
- a mode register coupled with the volatile memory and programmable, by the control circuit, with information that configures the volatile memory to enable transfer of the data to the NVM.
