Abstract
Various embodiments comprise apparatuses and methods including a method of reconfiguring partitions in a memory device as directed by a host. The method includes managing commands through a first interface controller to mapped portions of a first memory not having an attribute enhanced set, and mapping portions of a second memory having the attribute enhanced set through a second interface controller. Additional apparatuses and methods are described.
Claims21
A method, comprising:
- managing commands through a first interface controller to mapped portions of a first memory not having an attribute enhanced set;
- mapping portions of a second memory having the attribute enhanced set through a second interface controller;
- configuring the first interface controller to be aware of the existence of the second interface controller;
- and
- configuring the second interface controller not to be aware of the first interface controller.
2 more elements
A method, comprising:
- managing commands through a first interface controller to mapped portions of a first non-volatile memory, the first memory not including an attribute enhanced set;
- managing commands through a second interface controller to mapped portions of a second non-volatile memory, the second memory including an attribute enhanced set;
- inhibiting responses to a host from the second interface controller;
- and
- generating the responses to the host from the first interface controller.
2 more elements
A method, comprising:
- managing commands through a first interface controller to mapped portions of a first memory without an attribute enhanced set, the first memory comprising NAND flash;
- and
- mapping portions of a second memory with the attribute enhanced set through a second interface controller, the second memory comprising Phase-Change Memory (PCM), the first memory and the second memory forming portions of an embedded multi-media card (e-MMC) device;
- and
- providing responses to a host from the second interface controller when the first interface controller is in a power saving mode and requests have been sent from the host to the first interface controller.

- and
- generating the responses to the host from the first interface controller.
