摘要:
One exemplary storage control device for a storage medium includes a controller and a voltage detector, where the controller controls data access of the storage medium, and the voltage detector monitors a power signal and asserts a detection signal to notify the controller when anomaly of the power signal is detected. Another exemplary storage control device for a storage medium includes a voltage detector and a controller, where the voltage detector monitors a power signal to generate a detection signal, and the controller controls data access of the storage medium. In addition, the controller enters a first operational state when the detection signal indicates that a voltage level of the power signal falls within a first voltage range, and enters a second operational state when the detection signal indicates that the voltage level of the power signal falls within a second voltage range.

A method for increasing the internal memory in a processor. The method includes providing an extended memory in the processor, adding bits to data addresses and register addresses with an address extender, and adding bits to stack addresses with a stack pointer generator so that the processor is capable of accessing memory addresses larger than the bit width of the command set of the processor. The method also includes carrying over the bits when the stack address exceeds the limit of the conventional memory and accessing the stack data exceeding the limit of the conventional memory in the extended memory.

The invention provides a nonvolatile memory controller. In one embodiment, the nonvolatile memory controller receives new data for writing a nonvolatile memory from a host, and comprises a signature calculating circuit, a signature buffer, a signature comparison circuit, a data comparison circuit, and a nonvolatile memory interface circuit. The signature calculating circuit calculates a first signature according to the new data. The signature buffer outputs a second signature corresponding to old data stored in the nonvolatile memory, wherein the old data has the same logical address as that of the new data. The signature comparison circuit determines whether the first signature is identical to the second signature. The nonvolatile memory interface circuit writes the new data to the nonvolatile memory when the first signature is determined to be different from the second signature by the signature comparison circuit.
