Assignee: SEAGATE TECHNOLOGY LLC
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A data storage device, comprising:
a non-volatile memory (NVM) arranged as a main store for user data;
a controller configured to transfer the user data between the NVM and an external client (host);
a buffer memory formed of ferroelectric field effect transistors (FeFETs) arranged as a temporary storage location to store the user data and control information during said transfers by the controller, the controller comprising a monitor circuit configured to monitor operation of the FeFETs during said transfers and an optimization circuit configured to adjust at least one operational parameter associated with the FeFETs responsive to the monitored operation by the monitor circuit,
wherein the NVM comprises control lines having a first width, and wherein the FeFETs in the buffer memory have a control lines with a second width, the second width being larger than the first width; and
wherein the monitored operation by the monitor circuit comprises determination of data aping of data stored to the FeFETs, and the at least one operational parameter adjusted by the optimization circuit comprises the data aping of data stored to the FeFETs.
