Abstract

A method for performing encoding format conversion with integer arithmetic operations and a system performing the method are provided. The system includes a target device that adopts a power-management bus (PMBus), and operates an embedded system that is only capable of integer arithmetic operation without any floating-point unit. In the method, a floating-point arithmetic encoding format value is inputted. After a logarithm value of the floating-point value is obtained by extracting an exponent value from a binary representation of the floating-point value, a new exponent value can be obtained through a control flow. A new mantissa value is then calculated according to the floating-point value, the exponent value and the new exponent value. A new value that is a linear encoding format value converted from the floating-point arithmetic encoding format value is generated by combining the new exponent value and the new mantissa value.

Abstract

A pressable portable storage device includes an outer housing, a main body fixedly accommodated inside the outer housing, an inner housing slidably accommodated in a sliding space between the main body and the outer housing, an elastic unit connected between the main body and the inner housing, and a linear spring. The main body has a terminal port exposed outside the outer housing. The inner wall of the outer housing is formed with a protrusion. The linear spring has a first end disposed on the inner housing and a second end formed with a guiding hook pointing toward the inner wall of the outer housing. When the inner housing slides to sleeve the terminal port, the guiding hook moves along an outer edge of the protrusion to drive the linear spring to deform for providing a first spring force, and the elastic unit deforms for providing a second spring force.

Abstract

A flash memory device with a wear-leveling mechanism includes at least one flash memory, a hot list, a bitmap, a source pointer, and a controller. The controller obtains a physical memory block with high erase count through the hot list, an erase count of the physical memory block, and an overall average erase count of the flash memory device. The controller further finds out a physical memory block which stores static data through managing the bitmap and the source pointer. The controller moves the static data to the physical memory block with high erase count, and releases the physical memory block which stores the static data to avoid the physical memory block with high erase count being worn down increasingly more seriously.

Abstract

A flash memory controller with automatic interface mode switching is applied to a flash memory apparatus with a plurality of flash memories and the controller contains: a memory interface, a microprocessor, and an interface mode controller. The microprocessor recognizes the supported interface mode of every flash memory connected with the memory interface in an initial setting process, and individually sets the corresponding interface mode setting value into the interface mode controller. Thus, when the flash memory apparatus is operating in a normal operation state, the interface mode controller can output the corresponding interface mode setting value according to the present enabled flash memory, and the memory interface can adjust and switch the interface mode according to the interface mode setting value outputted by the interface mode controller. Thereby, the present invention can achieve the purpose whereby the flash memory apparatus can speed up accessing and increase efficiency.

Abstract

A method for memory space management is disclosed. It uses a resident program loaded into an operation system or the controller of a storage device to monitor the storage space and the resource allocation of the file system of the storage device. The status of the logical address with an erased and invalid data mapped with a physical block is checked via a L2P mapping table. By using a data erase instruction, the controller modifies the L2P mapping table to cancel the link relation between the physical block and the logical address and erase the physical block to release the memory space. Finally, the check location is stored for a next check. The method for memory space management improves the access speed and the usage life of the storage device.

Abstract

A storage system with a data recovery function and its method reduce errors in a storage medium to a recoverable range of a general ECC function by repeating a testing and recovery procedure for one or more times to assure the accuracy of reading data and enhance the data reliability effectively. The data recovery procedure includes the steps of providing test data by a test data generator of the storage system, writing the test data into a memory block where error data is found, finding an error bit by reading the test data, reducing the error to a recoverable range of the ECC technique by the recovery procedure. If the error bit cannot be found or reduced to a recoverable range of the ECC technique within an upper limit of the number of tests, the memory block is marked as bad.
