Abstract:
The system and apparatus for managing flash memory data includes a host transmitting data, wherein when the data transmitted from the host have a first time transmission trait and the address for the data indicates a temporary address, temporary data are retrieved from the temporary address to an external buffer. A writing command is then executed and the temporary data having a destination address are written to a flash memory buffer. When the flash memory buffer is not full, the buffer data are written into a temporary block of the flash memory. The writing of buffer data into the temporary block includes using an address changing command, or executing a writing command to rewrite the external buffer data to the flash memory buffer so that the data are written into the temporary block.

Abstract:
A method for supporting an unrecognizable flash memory, at least including steps of sending a parameter table comprising strings for error checking to a specified address, checking if the identification is unknown, reading the specified address in the flash memory to determine its cycle if the identification is unknown, checking if the strings for error checking are correctly read, and accessing the system code of the flash memory.
Abstract:
A method for accessing a downgrade memory and a downgrade memory apparatus are provided. The downgrade memory apparatus comprises at least one management unit and a controller. The management unit comprises a plurality of blocks, each block having a plurality of pages, and each page having a plurality of sectors, the downgrade memory having a plurality of non-accessible sectors. The controller is configured to parse a write command corresponding to a special block, to select at least one accessible sector according to a status information of the special block and to program the write command to the special block, wherein the status information indicates at least one non-accessible sector in the special block. Thereby the method and the apparatus of downgrade memory may as well omit the non-accessible sectors as enhance the usage memory capacity in accordance with the status information.
Abstract:
A resistance compensation circuit and a method thereof for tuning frequency, includes several resistors serially connected to one another, several transistors, each of which connects across one of the corresponding resistances, and a register electrically connected to the gates of the transistors. A control signal controls the switching of the transistors either to compensate the process variation of the resistance through the register or to tune the working frequency of the Integrated circuit.
Abstract:
A non-volatile memory array structure includes N bit lines, M first word lines, M×N first memory cells, a second word line, n repair circuits and a sense amplifier. The N bit lines and M first word lines are interlaced to control the M×N first memory cell. The second word line is placed across the n bit lines. Each of the repair circuits is electrically connected between the corresponding bit line and the sense amplifier. M and N are natural number.
Abstract:
An analog input/output (I/O) circuit contains a pad, an analog IP (Intellectual Property) circuit, and a transmission gate. The pad is connected to the analog circuit IP. The transmission gate is configured between the pad and analog circuit IP, and therefore any signal between the pad and analog circuit IP must pass through the transmission gate. In normal operation, the transmission gate allows analog signals to transfer between the pad and analog circuit IP. If an ESD (Electrostatic Discharge) current is induced from the pad, the transmission gate discharges the current and protects the analog circuit IP.
Abstract:
A memory stick convert device includes an upper housing and lower housing and a convert interface. An assembly of the upper housing and the lower housing has the same type of connector as the Memory Stick (Pro) Duo does at an end. The assembly includes a cavity to accommodate a Micro-SD stick. The convert interface is sandwiched between the upper housing and the lower housing to convert signal formats between the Memory Stick (Pro) Duo and the Micro-SD.
Abstract:
A package and a method for saving space required by I/Os of a chip are described. In this method, a plurality of general I/Os and at least one special I/O are allocated in different areas. When the chip is attached to a circuit board, the special I/O is adjacent to a non-soldering area of the circuit board and the general I/Os are adjacent to a soldering area of the circuit board. The special I/O is located on the bottom surface of the chip. When the chip is attached to the circuit board, the special I/O is adjacent to a soldering resistant layer and the general I/Os are electrically connected to signal lines on the circuit board.
