Abstract
A device that provides garbage collection read throttling includes at least one processor that is configured to receive a request to perform a garbage collection read command on one of a plurality of flash memory circuits. The at least one processor is configured to determine whether garbage collection read throttling is enabled, such as when a garbage collection read throttling criterion is satisfied. The at least one processor is configured to buffer the garbage collection read command when garbage collection read throttling is enabled and perform the garbage collection read command when garbage collection read throttling is disabled. When the garbage collection read throttling is enabled and the garbage collection read command is buffered, the at least one processor is configured to perform the buffered garbage collection read command when garbage collection read throttling is subsequently disabled.
