HOST CONTROL OF BACKGROUND GARBAGE COLLECTION IN A DATA STORAGE DEVICE

摘要

An apparatus includes a flash memory data storage device (100) and a host (106, 350) operably coupled to the data storage device (100) via an interface (108). The flash memory data storage device (100) includes a plurality of memory chips (118a, 118b, 218). The host (106, 350) includes a host activity monitoring engine (360) configured to monitor (402) activity of the host (106, 350) and a garbage collection control engine (358) configured to control (408) the background garbage collection performed on the memory chips (118a, 118b, 218).
