Apparatus and method for access operations during voltage transitions
By introducing a transition mode setting in the memory device, ensuring that the data is latched in a single data rate mode during voltage change, the problem of mismatch between the data and the clock signal caused by voltage change is solved, and the alignment between the data and the clock signal is achieved without shutting down.

Abstract
This disclosure describes devices, systems, and methods for access operations during voltage transitions. The memory may receive a system voltage and a clock signal from the controller. The controller may be used to time operations such as write operations, however, the internal clock signal of the memory may depend on a voltage. The memory operates at dual data rates relative to the clock signal. During a transition period in which the voltage changes between levels, the memory is switchable to a transition mode in which the memory operates at a single data rate.
