Data may be stored in a non-volatile memory array in adaptive metablocks that are configured according to the locations of data boundaries in the data. Data may be stored in an intermediate format and later copied to adaptive metablocks configured for the data. Data in intermediate format may be stored in non-volatile random access memory or in a portion of the non-volatile memory array.

Data in data runs are stored in a non-volatile memory array in adaptive metablocks that are configured according to the locations of data boundaries. A serial flash buffer is used to store some data, while other data are directly stored in non-volatile memory. Data may be stored with alignment to data boundaries during updating of the data to improve efficiency of subsequent updates.

In a nonvolatile memory system that includes a block-erasable memory array, records are individually maintained for certain classifications of blocks. One or more lists may be maintained for the blocks, an individual list ordered according to a descriptor value. Such ordered lists allow rapid identification of a block by descriptor value.

The invention discloses an inter-standard switching method ensuring lossless transmission of packet-switched domain data. When standard switching between GSM and TD-SCDMA/WCDMA is carried out, uplink of a data packet is suspended, the received data packet is temporarily stored and standard switching of an access layer is carried out; then, data plane switching is launched and data channels under new standard are established on the data plane; later, the data channels before switching are released; finally, unsent data packets and temporarily stored data packets are ranked according to the serial number and are sent to the network side through the data channels under new standard. The invention also discloses an inter-standard switching device ensuring lossless transmission of packet switch domain data. By adopting the invention, integrity of the packet-switched domain data packet can be realized when a mobile terminal is switched between the TD-SCDMA/WCDMA system and the GSM system, and continuity, correctness and smoothness of data transmission after switching are ensured.
