A microcontroller is configured to use the random access memory to cache data issued from the host before writing the data into the flash memory. The microcontroller is further configured to allocate the blocks of the flash memory to provide a first run-time write block containing multi-level cells and a second run-time write block containing single-level cells. Under control of the microcontroller, each physical page of data uploaded from the random access memory to the first run-time write block contains sequential data, and random data cached in the random access memory to form one physical page is written into the second run-time write block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data storage device and flash memory control method","description":"A data storage device with flash memory and a flash memory control method are disclosed, in which the flash memory includes multi-level cells (MLCs) and single-level cells (SLCs).
