Data storage device and method for dynamically determining a buffer size

Abstract

A data storage device includes a memory device and a memory controller. The memory device has a corresponding total storage capacity and includes multiple memory blocks. The total storage capacity is set to a maximum storage capacity provided by the memory blocks by default. The memory blocks include one or more predetermined memory blocks configured as a buffer to receive data from a host device. The memory controller is coupled to the memory device to access the memory device. In response to setting of a maximum amount of write data, the memory controller determines a value of the total storage capacity according to the maximum amount of write data, and determines a number of said one or more predetermined memory blocks according to the value of the total storage capacity and the maximum storage capacity.
