Technology to dynamically modulate read granularity of a memory device. A computing system may include a controller and one or more memory devices coupled to the controller, the one or more memory devices including instructions, which when executed by the controller, may cause the computing system to determine whether a read to a memory device satisfies a sub-page read policy. In addition, the instructions, when executed, may cause the computing system to 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. Moreover, the instructions, when executed, may cause the computing system to issue a full-page read command to retrieve the data at full-page granularity when the read does not satisfy the sub-page read policy or when a read for a segment of sequentially stored data does not satisfy the sub-page read policy.
