Abstract: A data storage device includes a controller and a memory die. The controller includes a host interface and a memory interface. A method includes receiving a message from a host device via the host interface. The message indicates that the host device is to perform a first adjustment process associated with the host interface. The method further includes performing a second adjustment process associated with the memory interface in response to receiving the message indicating that the host device is to perform the first adjustment process.

Abstract: A data storage device includes a controller and a memory. The controller includes a host interface and a memory interface. The controller writes a first data test to a memory device through either the host interface or the memory interface at a first voltage level to determine a first write value. The controller reads the first data test written to the memory device through the same interface, either the host interface or the memory interface, at a second voltage level to determine a first read value. The controller then changes the second voltage to a third voltage based on a determination of whether the first read value is equal to the first write value to dynamically alter a working voltage level of the storage device in response to changing process, voltage, and temperature conditions.

Abstract: A data storage device includes a controller and a memory. The controller includes a host interface and a memory interface. The controller performs a first operation on the memory through the memory interface at a first frequency associated with the host interface to determine a first data pattern. The controller performs a read operation on the memory through the memory interface at a second frequency to determine a second data pattern. The controller changes the first frequency by a predetermined amount until the first frequency is equal to a maximum operating frequency having an associated risk of a setup/hold violation that is below a predetermined probability.

Abstract: A memory system and method are provided for adaptive auto-sleep and background operations. In one embodiment, a controller of a memory system measures an amount of time between when the memory completes an operation and when the controller receives a command to perform another operation in the memory. The controller adjusts a time period after which the controller enters an auto-sleep mode and/or starts a background operation based on the measured amount of time. Other embodiments are disclosed.
