20100138580 | MEMORY CARD ADAPTER - A card adapter includes a plurality of memory card interfaces for interfacing with a plurality of memory cards, each of the memory cards having its own file system, and a host interface for interfacing a host of the memory cards. A controller of the card adapter interfaces with the plurality of memory card interfaces and with the host interface and controls operation of the memory cards. The card adapter may have several modes of operation, one of which involves emulating, on the host, by the controller, a virtual file system that represents a unified image of the file systems of two or more memory cards. In another mode of operation of the card adapter the controller establishes presents to the host only one file system of a memory card. | 06-03-2010 |
20110228604 | PRELOADING DATA INTO A FLASH STORAGE DEVICE - Programmer's data is initially stored in a memory device of the storage device by using an MBC storage scheme. After the storage device is embedded in a host device, the programmer's data is internally read from the memory device by using conventional read reference voltages, and the number of erroneous data bits in the programmer's data is calculated. If the programmer's data includes an uncorrectable number of erroneous data bits, the programmer's data is iteratively reread by using unconventional read reference voltages with decreased levels. The iteration process, which includes decreasing the level of the read reference voltages and recalculating the number of erroneous data bits, is terminated when the number of erroneous data bits in the programmer's is less than or equals a predetermined number of erroneous data bits, after which the storage device restores the programmer's data and conventionally rewrites it into the memory device. | 09-22-2011 |
20130138866 | METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR PROVIDING BASIC INPUT/OUTPUT SYSTEM (BIOS) DATA AND NON-BIOS DATA ON THE SAME NON-VOLATILE MEMORY - Methods, systems, and computer readable media for providing BIOS data and non-BIOS data on the same non-volatile memory. According to one aspect, a system for providing BIOS data and non-BIOS data on the same non-volatile memory includes a controller for controlling access by a host to a non-volatile memory for storing data, the data including BIOS data and non-BIOS data. The controller includes a first bus interface for communicating data to and from the host via a first bus of a first bus protocol, a second bus interface for communicating data to and from the host via a second bus of a second bus protocol, and a third interface for communicating data to and from the non-volatile memory. The first bus comprises a bus that is operable after power-on reset and before BIOS is accessed. | 05-30-2013 |
