Intelligent scheduling of background operations in memory

摘要

A memory system or flash card may include an algorithm for identifying a pattern in a sustained or continuous write operation. In one example, a video recording device may be a host that continuously writes data to a memory card in an identifiable pattern. The pattern identification algorithm may be stored in the firmware of the memory card and used to schedule background operations during the predicted idle times in which the host is not writing data to the memory card.

1. A flash memory device comprising:
a non-volatile storage having an array of memory blocks storing data; and a controller in communication with the non-volatile storage, the controller is configured for:
receiving data chunks from a host to be stored in the non-volatile storage;identifying, with firmware on the flash memory device, a pattern based on the received data chunks, wherein the pattern comprises data chunks and idle time between successive data chunks; andscheduling background operations during the idle time.
