Abstract
A multilevel memory subsystem includes a persistent memory device that can access data chunks sequentially or randomly to improve read latency, or can prefetch data blocks to improve read bandwidth. A media controller dynamically switches between a first read mode of accessing data chunks sequentially or randomly and a second read mode of prefetching data blocks. The media controller switches between the first and second read modes based on a number of read commands pending in a command queue.
