Technology to dynamically modulate memory device read granularity

An apparatus comprising:

• a substrate;
• and
• logic coupled to the substrate, wherein the logic includes one or more of configurable logic or fixed-functionality hardware logic, the logic coupled to the substrate to:
• determine whether a read to a memory device satisfies a sub-page read policy;
• and
• issue a sub-page read command to retrieve data from the memory device at sub-page granularity when the read satisfies the sub-page read policy, the logic further to:
• issue a persistent state command to enter the memory device to a sub-page state or a full-page state, wherein the sub-page state allows the memory device to read data at the sub-page granularity until a full-page read is required, and wherein the full-page state allows the memory device to read data at a full-page granularity until a sub-page read is required;
• or
• issue a non-persistent toggle state command that is to disable a default state of the memory device to allow the memory device to retrieve data at granularity specific to a non-default state, implement one read at the granularity specific to the non-default state, and re-enable the default state when the one read is complete.

At least one non-transitory computer readable storage medium comprising a set of instructions, which when executed by a processor, cause the processor to:

• determine whether a read to a memory device satisfies a sub-page read policy;
• and
• issue a sub-page read command to retrieve data from the memory device at sub-page granularity when the read satisfies the sub-page read policy, the processor further to:
• issue a persistent state command to enter the memory device to a sub-page state or a full-page state, wherein the sub-page state allows the memory device to read data at the sub-page granularity until a full-page read is required, and wherein the full-page state allows the memory device to read data at a full-page granularity until a sub-page read is required;
• or
• issue a non-persistent toggle state command that is to disable a default state of the memory device to allow the memory device to retrieve data at granularity specific to a non-default state, implement one read at the granularity specific to the non-default state, and re-enable the default state when the one read is complete.

• prepare to dispatch a separate read command for each segment;
• determine whether each read for each segment of sequentially stored data satisfies the sub-page read policy;

• issue a separate sub-page read command to retrieve each segment of sequentially stored data at sub-page granularity for which a corresponding read satisfies the sub-page read policy and issue a separate full-page read command to retrieve each segment of sequentially stored data at full-page granularity for which a corresponding read does not satisfy the sub-page read policy.
