    摘要: A method includes, in one non-limiting embodiment, sending a request from a mass memory storage device to a host device, the request being one to allocate memory in the host device; writing data from the mass memory storage device to allocated memory of the host device; and subsequently reading the data from the allocated memory to the mass memory storage device. The memory may be embodied as flash memory, and the data may be related to a file system stored in the flash memory. The method enables the mass memory storage device to extend its internal volatile RAM to include RAM of the host device, enabling the internal RAM to be powered off while preserving data and context stored in the internal RAM.

    摘要: The specification and drawings present a new method, apparatus and software product for performance enhancement of a memory device (e.g., a memory card) using a pre-erase mechanism. The memory device can be, e.g., a memory card, a multimedia card or a secure digital card, etc. A new command or commands can be used to inform a memory device controller when the data in one particular sector, allocation unit or block can be deleted. Using that information the memory device controller then can be able to do some internal maintenance, e.g., by moving valid data from a fragmented erase block to another so that the fragmented erase block can be cleared and erased for future use as well as performing effective wear levelling maintenance and write performance optimization.

    摘要: A method and apparatus for addressing a plurality of mass memory components coupled to a host device. The memory components can be arranged in a chain or in a ring configuration. In a ring, each memory component receives a bit pattern from the preceding stage and sends a bit pattern to the next stage in consecutive clock periods. Based on the received bit pattern, a recipient component knows the bus width between itself and the sending component. In a chain, each memory component also sends the received bit pattern back to the preceding stage. The memory component can generate its own address by counting clock periods. Alternatively, a recipient component changes its received bit pattern before sending the bit pattern to the next stage. As such, the recipient component knows its address based on the received bit pattern.

    摘要: Methods, systems and devices for configuring access to a memory device are disclosed. The configuration of the memory device may be carried out by creating a plurality of access profiles that are adapted to optimize access to the memory device in accordance with the type of access. Accordingly, when an application with specific memory access needs is initiated, the memory access profile that is most optimized for that particular access need is utilized to configure access to the memory device. The configuration may be effected for a portion of the memory device, a partition of the memory device, or even one single access location on the memory device.

    摘要: The present invention relates to a method for addressing the memory locations of a memory card. There are several memory locations in a memory card for storing data, in which case in order to address a specific memory location an address is formed. At least one parameter is stored in the memory card, on the basis of which parameter the number of memory locations of a memory card can be calculated, and a specific number of bits is reserved for said at least one parameter. In the method, two or more memory locations are addressed with one address, and/or the number of bits that can be used in an address is increased. The invention also relates to a system and a memory card in which the method is applied.
