International Classification:

G06F 12/02

US Classification:

711103

Abstract:

Storage device FirmWare (FW) and manufacturing software techniques include access to FW images and communication of a manufacturing software tool. The manufacturing software tool enables download of the FW images into an I/O device and controlling a manufacturing test of the I/O device that is a storage device providing a storage capability. Execution of the downloaded FW images enables an I/O controller of the I/O device to provide the storage capability via operation with one or more selected types of flash memory devices. The selected types are selected from a plurality of flash memory types that the I/O controller is capable of operating with by executing appropriate ones of the FW images. Optionally the manufacturing test includes testing the storage capability of the I/O device. The techniques further include an SSD manufacturing self-test capability.

International Classification:

G06F 12/02

US Classification:

711103

Abstract:

A method for using a partitioned flash transition layer is disclosed. Step (A) receives, at an apparatus from a host, a write command having first write data. Step (B) generates second write data by compressing the first write data in the apparatus. The second write data generally has a variable size. Step (C) stores the second write data at a physical location in a nonvolatile memory. The physical location is a next unwritten location. Step (D) returns, from the apparatus to the host in response to the write command, an indication of the physical location.
