Abstract: A memory controller coupled to a memory device and a host device and configured to control access operations of the memory device includes a buffer memory, a host interface, a microprocessor and a data protection engine. The host interface is coupled to the host device and configured to write data received from the host device into the buffer memory and issue a buffer memory write complete notification after the data has been written in the buffer memory. The microprocessor is configured to trigger a data protection operation in response to the buffer memory write complete notification. The protection engine is configured to perform the data protection operation to generate corresponding protection information according to the data written in the buffer memory. The microprocessor is configured to directly trigger the data protection operation after confirming that the data has been written in the buffer memory.

Abstract: A memory controller coupled to a memory device and configured to control access operations of the memory device includes a data protection engine and a microprocessor. The data protection engine is configured to generate protection information according to data received from a host device. The microprocessor is configured to detect a status of the memory device in response to one or more write operations for writing the data to the memory device, determine whether a portion of the data has to be excluded when generating the protection information corresponding to the data according to the status and accordingly generate a determination result, and store the protection information and the determination result together in the memory device. The determination result indicates which portion of the data is utilized to generate the protection information.

Abstract: A data-downloading technique for a data storage device before soldering the data storage device into a product. The data storage device uses a flash memory to provide first-type blocks (using single level cells) and second-type blocks (using multi-level cells). Before soldering the data storage device onto a printed circuit board, a controller of the data storage device allocates the first-type blocks to store data from a host. When the allocated number of first-type blocks reaches an upper limit, the controller changes to allocate the second-type blocks to store data from the host. When detecting that the controller has changed to allocate the flash memory to provide the second-type blocks to receive data from the host, the controller returns a fail message to the host to indicate unreliable write operations prior to soldering.

Abstract: A memory system with a programming status is provided. The memory includes at least one first memory, at least one second memory and a controller. Each of the at least one first memory includes a plurality of memory regions to store data. Each of the at least one second memory includes a plurality of memory regions for programming the data from the at least one first memory. The controller is coupled to the second memory and utilized to record a programming status of the data. Whether the programming is successful or not is checked when the at least one first memory or the at least one second memory is going to be implemented by inquiring the programming status, and the at least one first memory stores the data until the programming is checked to be successful.

Abstract: A data storage device includes a FLASH memory and a controller. The FLASH memory includes a plurality of blocks wherein each of the blocks includes a plurality of pages. The controller is coupled to the FLASH memory and utilized to execute a garbage-collection process on the FLASH memory according to a number of spare blocks in the FLASH memory and a number of inefficient blocks where most of the pages are spare in the FLASH memory. The garbage-collection process is utilized for merging at least two inefficient blocks to release at least one spare block from the inefficient blocks.
