Abstract
An information writing method is applied to an non-volatile dual in-line memory module (NVDIMM), the NVDIMM includes an NVDIMM controller and a non-volatile memory (NVM), and the method includes receiving, by the NVDIMM controller, a sanitize command from a host, where the sanitize command is used to instruct the NVDIMM controller to sanitize data in the NVM using a first write pattern, and the first write pattern is one of at least two patterns of writing information into the NVM, and writing, by the NVDIMM controller, information into the NVM according to the sanitize command.
Claims20
An information writing method, implemented by a non-volatile dual in-line memory module (NVDIMM), the information writing method comprising:
- receiving a sanitize command from a host, wherein the sanitize command is configured to instruct an NVDIMM controller to sanitize data in a non-volatile memory (NVM), and wherein the NVDIMM comprises the NVDIMM controller and the NVM;
- and
- writing information into the NVM according to the sanitize command.
An information writing method performed by a host, wherein the information writing method comprises:
- generating a sanitize command, wherein the sanitize command is configured to instruct a non-volatile dual in-line memory module (NVDIMM) controller in an NVDIMM to sanitize data in a non-volatile memory (NVM), wherein the NVDIMM comprises the NVDIMM controller and the NVM;
- and
- sending the sanitize command to the NVDIMM controller.
A non-volatile dual in-line memory module (NVDIMM), comprising:
- a non-volatile memory (NVM);
- and
- an NVDIMM controller coupled to the NVM and configured to:
- receive a sanitize command from a host, wherein the sanitize command is configured to instruct the NVDIMM controller to sanitize data in the NVM;
- and
- write information into the NVM according to the sanitize command.
A computing system, comprising:
- a non-volatile dual in-line memory module (NVDIMM) comprising an NVDIMM controller and a non-volatile memory (NVM);
- and
- a processor coupled to the NVDIMM and configured to:
- generate a sanitize command, wherein the sanitize command is configured to instruct the NVDIMM controller to sanitize data in the NVM;
- and
- send the sanitize command to the NVDIMM controller.
