SOLID-STATE STORAGE DEVICES THAT REDUCE READ TIME FOR READ TIME-SENSITIVE DATA

摘要

Disclosed herein is a solid-state storage device that reduces read time for read time- sensitive data ("RTS data"). Data-characterizing logic characterizes incoming data from a host system as primary data including the RTS data or secondary data including non-RTS data. Memory-cell programming schemes include a primary data-programming scheme for a reduced read-frequency zone for the primary data and a secondary data-programming scheme standard read-frequency zone for the secondary data. Data routing logic routes the primary data to a plurality of physical pages corresponding to lower logical pages of a plurality of logical pages in the at-least-one reduced read-frequency zone with assistance by a logical-to-physical address translator. The lower logical pages require fewer read operations than upper logical pages of the plurality of logical pages to read the primary data, which results in a reduction of the read time for the RTS data in the at-least-one reduced read-frequency zone.
