TN-29-85: UFS Memory Health Report for Mobile Devices
Introduction
Technical Note
Micron UFS Memory Health Report for Mobile Devices
Introduction
This technical note describes how to obtain the extended health report information for Micron's UFS
devices listed in the table below. The extended health report information is accessed via proprietary
vendor-unique (VU) commands issued through the SCSI interface of the UFS device.
Because UFS devices are Managed NAND components, and NAND cells are stressed by the continuous
use of UFS devices, it is important to understand how usage affects the device and the device data. The
extended health report is a resource that allows customers to monitor a device's media usage and the
length of time that the device can be cycled.
The method of obtaining the extended health report information can be applied to the following
Micron UFS devices.
