Method for erasing data entity in memory module

A memory module, comprising:

• a memory device;
• and
• a memory controller configured to communicate with an external host and to communicate with the memory device;
• the memory controller configured to:
• store a data entity in at least two sectors of the memory device, the data entity including at least first data and second data;
• receive a first command to select a mode in which a second command indicative of erasing the first data instructs the memory controller to erase at least the first data and the second data stored in the memory device;
• maintain context information of the data entity, the context information comprising at least a pointer to at least one of the at least two sectors of the memory device;
• receive the second command indicative of erasing the first data;
• and
• erase the at least two sectors of the memory device based at least on the context information, the mode selected via the first command, and the second command.

One or more non-transitory computer-readable media comprising computer-executable program code which, when executed by at least one memory controller of a memory module, causes the memory module to:

• store a data entity in at least two sectors of a memory device, the data entity including at least first data stored in a first sector of the at least two sectors and second data stored in a second sector of the at least two sectors;
• receive a first command to select a mode in which a second command indicative of erasing the first sector erases at least the first sector and the second sector of the memory device;
• maintain context information of the data entity, the context information comprising at least a pointer to at least one of the at least two sectors of the memory device;
• receive the second command indicative of erasing the first sector;
• and
• erase the at least two sectors of the memory device based at least on the context information, the mode selected via the first command, and the second command.

A memory module, comprising:

• a memory device;
• means for communicating with an external host and with the memory device;
• means for storing a data entity in at least two sectors of the memory device, the data entity including at least first data stored in a first sector of the at least two sectors and second data stored in a second sector of the at least two sectors;
• means for receiving a first command to select a mode in which a second command indicative of erasing the first sector instructs a means for erasing to erase at least the first sector and the second sector of the memory device;
• means for maintaining context information of the data entity, the context information comprising at least a pointer to at least one of the at least two sectors of the memory device;
• means for receiving the second command indicative of erasing the first sector;
• and
• the means for erasing the at least two sectors of the memory device based at least on the context information, the mode selected via the first command, and the second command.

A host device, comprising:

• a host controller configured to communicate with a memory module,
• the host controller further configured to:
• cause the memory module to store a data entity in at least two sectors of the memory module, the data entity including at least first data stored in a first sector of the at least two sectors and second data stored in a second sector of the at least two sectors, the data entity associated with a context identifier used for one or more write operations associated with the data entity;
• transmit a first command to the memory module to select a mode in which a second command indicative of erasing the first sector instructs the memory module to erase multiple sectors of the memory module;
• and
• transmit the second command to the memory module, the second command indicative of erasing the first sector.
