Abstract
A storage device manages a read look ahead (RLA) buffer with fluctuating RLA caching. The storage device includes a memory device to store data in a format including upper, middle, and lower pages and an RLA buffer to store data retrieved from the memory device. When a controller on the storage device receives a host read request, the controller predicts data to be included in a subsequent host read request. The controller then determines a set of pages storing the predicted data, identifies latency-oriented pages in the set of pages, retrieves data from the latency-oriented pages, and stores the data in the RLA buffer. When the storage device receives the subsequent host read request including the predicted data, the controller reads a first portion of the predicted data from the RLA buffer and a second portion of the predicted data from the memory device.
