APPARATUS, SYSTEM, AND METHOD FOR MANAGING COMMANDS OF SOLID-STATE STORAGE USING BANK INTERLEAVE

摘要

Efficiently managing commands in a solid-state storage device (102) that includes a solid-state storage (110) arranged in two or more banks (214). Each bank (214) is separately accessible and includes two or more solid-state storage elements (216, 218, 220) accessed in parallel by a storage input/output bus (210). The solid-state storage (110) includes solid-state, non- volatile memory. The solid-state storage device (102) includes a bank interleave controller (324) that directs one or more commands to two or more queues, where the one or more commands are separated by command type into the queues. Each bank includes a set of queues in the bank interleave controller. Each set of queues includes a queue for each command type. The bank interleave controller (324) coordinates among the banks execution of the commands stored in the queues, where a command of a first type executes on one bank (214a) while a command of a second type executes on a second bank (214b-n).
