The invention relates to a method for use in a system comprising a host device and at least one peripheral device which are enabled to interact with each other. In order to improve the flexibility of the system, the method comprises a step of transmitting information indicative of a time required for an initialization of the at least one peripheral device from the at least one peripheral device to the host device, and a step of evaluating in the host device the information indicative of a time required by the at least one peripheral device for an initialization. The invention relates equally to a corresponding host device, to a corresponding peripheral device, to a corresponding system and to corresponding software program products.

This invention relates to a method permanently write protecting a portion of a memory card. According to the invention a bit indicating permanent write protection or permanent write protection of a portion of the memory card is set in the specific data register of the memory card to indicate that all the write protect groups protected with write protecting command are permanently write protected. In another embodiments of the invention special commands are used to control the write protection of the portion of the memory card. This invention also relates to a partially permanently write protected memory card. The invention further relates to an electronic device, a software, a system and a module utilizing the method of the invention.

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.

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.

Systems and methods for booting a host device(s) from a peripheral device(s), via an interface, such as an MMC/SD interface, with power terminals, a data bus with data bus terminals, a clock line with a clock terminal and a command line with command terminal. Power is provided to the power terminals, and the command terminal of the MMC/SD or analogous interface is set during power-up to low. The data bus is monitored for a start bit of data transmission.

A mode indexing table is used for listing the available modes in a multimode device. From information in the mode indexing table, a host recognizes the modes as listed in the table. The host has a mandatory initialization mode using a known technique, such that the device can enter into an initialization mode directly or via a boot function. During initialization, the host receives the remaining part of the table from the multi-mode device and recognizes the functionality of each of the listed modes in the table. Among the available modes, some modes are allowed to access data of other modes according to the level of access. The multimode device has some commands that can be used for direct mode switching.

The invention relates to a method of operating a storage component 10,30,40. In order to enable a verification of the integrity of the data in the storage component, it is proposed that first a write operation for storing data in a data storage area 11,31,41 of the storage component 10,30,40 is performed. Then, a completion status field 15,35,45 in the storage component 10,30,40 is updated, in case the write operation has been completed successfully. The updated completion status field 15,35,45 indicates that the write operation has been completed successfully. The invention relates equally to a corresponding storage component and to a corresponding system.

A method, system, device and software products for loading files or clips thereof from a unit including files or clips thereof over at least one interface to a data-processing unit. The arrangement according to the invention includes determining joint probabilities of the files or parts (“clips”) thereof, energy consumptions caused by their loading and a value for maximum energy consumption. A loading order is formed for the files or clips thereof as a function of the joint probabilities. Files or clips thereof are loaded over at least one interface in the loading order, and total energy consumption caused by the loading is determined until the value of the total energy consumption exceeds the value of the maximum energy consumption. At this point, loading of the files or clips thereof is interrupted.

The invention relates to a method of creating a virtual memory space in a memory. In order to improve the efficiency of the memory, the method comprises determining whether additional memory space is needed in the memory. If additional memory space is needed, selected portions of memory content stored in the memory are compressed. Memory space which is no longer needed by the compressed selected portions of memory content is released for use as virtual memory space. The invention relates equally to a memory manager controlling a memory accordingly, to a system comprising such a memory manager and a memory, and to a software realizing the steps of the method when running in a memory manager.
