IS4	Universal Flash Storage (UFS 2.0)

This course covers UFS 2.0 , which is the enhanced version of MMC standard

OBJECTIVES This course explains how SCSI commands are transported over UFS. The hardware layer is detailed, including the analog part. Using UniPro as a tunnel to transport upper protocols. The course explains how command can be queued, enabling multi-threading. The course describes the low power modes. Secure aspects, such as secure erase and authenticated transfers are explained. The UFS Host Controller Interface is also covered. A more detailed course description is available on request at training@ac6-training.com

Prerequisites Experience of mass-storage interface, such as SD/MMC, USB mass storage class or SATA is recommended.
