摘要： An apparatus and a method for executing host commands, which is performed by a host interface in a flash controller, to include: determining whether a preset number of successive unaligned host long-write commands have been detected, where a first starting logical block address (LBA) number of data to be written, which is requested by each unaligned host long-write command, does not align with a first physical page of one super page; if so, calculating an offset, so that a second starting LBA number of data to be written, which is requested by a host write command, plus the offset aligns with a first physical page of one super page; generating a third starting LBA number by adding the offset to the second starting LBA number; and storing an entry in an LBA shifting table, which includes information about the second starting LBA number and the offset.

摘要： The invention introduces a method for verifying memory interface, performed by a processing unit, to include: driving a physical layer of a memory interface to pull-high or pull-low a signal voltage on each Input-Output (IO) pin thereof to a preset level according to a setting; obtaining a verification result corresponding to each IO pin from the memory interface; and storing each verification result in a static random access memory (SRAM), thereby enabling a testing host to obtain each verification result of the SRAM through a test interface. The testing host may examine each verification result to know whether any unexpected error has occurred in signals on the IO pins of the memory interface.

摘要： The present invention provides a method for accessing a secure digital (SD) card, which includes a voltage supply pin for receiving voltage supply from a host, at least one ground pin, a clock pin for receiving a clock signal from a host, a command pin for receiving a command from a host, and four data pins for writing data into the SD card or reading data from the SD card. The method includes receiving, via the command pin, an address extension command including a first address from a host, receiving, via the command pin, an access command including a second address from a host, and accessing, via the data pins, at least a memory location of the SD card indicated by a third address, which is a combination of the first address and the second address. The access command indicates an access operation to be performed on the SD card selected from: a single read operation, a single write operation, a multiple read operation, a multiple write operation and an erase operation.

摘要： The invention introduces an apparatus for handling flash physical-resource sets, at least including a random access memory (RAM), a processing unit and an address conversion circuit. The RAM includes multiple segments of temporary space and each segment thereof stores variables associated with a specific flash physical-resource set. The processing unit accesses user data of a flash physical-resource set when executing program code of a Flash Translation Layer (FTL). The address conversion circuit receives a memory address issued from the FTL, converts the memory address into a relative address of one segment of temporary space associated with the flash physical-resource set and outputs the relative address to the RAM for accessing a variable of the associated segment of temporary space.

摘要： The invention introduces a method for performing data writes into a flash memory, at least including the steps: determining whether at least one host write command that requires to process immediately is presented in a submission queue (SQ) before performing a portion of a Host-Flash mapping (H2F) table update or a GC process; and executing the host write command that requires to process immediately in a batch and then performing the portion of the H2F table update or the GC process when the determination is positive.

摘要： A control method for a multi-channel non-volatile memory is shown. When reading a read target on the non-volatile memory, the controller increases the read count of the monitored unit to which the read target belongs and, based on the read count, determines whether to move data of the monitored unit covering the read target to a safe space to deal with reading interference. The monitored unit is smaller than a cross-channel management unit in read-count group. The controller accesses a parallel accessing space of the non-volatile memory in parallel through all of the channels, and allocates the parallel accessing space based on the cross-channel management unit.

摘要： The invention introduces an apparatus for segmenting a data stream, installed in a physical layer, to include a host interface, a data register and a boundary detector. The data register is arranged to operably store data received from the host side through the host interface. The boundary detector is arranged to operably detect the content of the data register. When the data register includes a boundary-lock pattern or a special symbol, the boundary detector outputs a starting address that the boundary-lock pattern or the special symbol is stored in the data register to an offset register to update a value stored in the offset register, thereby enabling a stream splitter to divide data bits of the data register according to the updated value of the offset register.
