Frame protocol of memory device

Techniques are described herein for a training procedure that identifies a frame boundary and generates a frame clock to identify the beginning and the end of a frame. After the frame training procedure is complete, a memory device may be configured to execute a frame synchronization procedure to identify the beginning of a frame based on the frame clock without the use of headers or other information within the frame during an active session of the memory device. During an activation time period after a power-up event, the memory device may initiate the frame training procedure. Once the frames are synchronized, the memory device may be configured to use that frame clock during an entire active session (e.g., until a power-down event) to identify the beginning of a frame as part of a frame synchronization procedure.
