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 first memory of the memory module to a second memory of the memory module;
- and
- in response to the command, programming, by the memory module, a first mode register of the first memory of the memory module with first information that configures the first memory of the memory module to enable transfer of the data from the first memory of the memory module to the second memory of the memory module.
An apparatus, comprising:
- a memory module including a first memory and a second memory;
- a control circuit coupled between the first memory of the memory module and the second memory of the memory module and configured to cause transfer of data from the first memory of the memory module to the second memory of the memory module in response to a command to perform a save operation;
- and
- a mode register included in the first memory of the memory module and configured to be programmed, by the control circuit, with information that configures the first memory of the memory module to enable transfer of the data to the second memory of the memory module.
An apparatus comprising:
- a memory module comprising a first memory and a second memory, wherein the first memory of the memory module comprises one or more memories, each memory of the one or more memories comprising a respective mode register;
- a host device coupled to the first memory of the memory module via a first bus;
- and
- a control circuit coupled to the host device via a second bus, coupled to the first memory of the memory module via a third bus, and coupled to the second memory of the memory module via a fourth bus, wherein the control circuit is configured to program the respective mode register of one of the one or more memories with information that configures the one of the one or more memories to enable transfer of data to the second memory.
