(83)
(84) The memory controller 520 may supply the input signals for controlling operation of the memory 510. For example, in the case of a NAND flash memory, the memory controller 520 may supply the command CMD and address signals. In examples of a NOR flash memory, the memory controller 520 may supply CMD, ADD, DQ and VPP signals. It will be appreciated that the memory controller 520 may control the memory 510 based on received control signals (not shown).
(85)
(86) The interface 515 may supply the input signals (for example, generated externally) for controlling operation of the memory 510. For example, in the case of a NAND flash memory, the interface 515 may supply the command CMD and address signals. In the example of a NOR flash memory, the interface 515 may supply CMD, ADD, DQ and VPP signals. It will be appreciated that the interface 515 may control the memory 510 based on received control signals (for example, generated externally, but not shown).
(87)
(88)
(89) Data (video, audio, etc.) may be input to and output from the memory 510 via the memory controller 520 by an encoder and decoder (EDC) 610. As shown by the dashed lines in
(90) The EDC 610 may encode data for storage in the memory 510. For example, the EDC 610 may perform MP3 encoding on audio data for storage in the memory 510. Alternatively, the EDC 610 may perform MPEG encoding (e.g., MPEG2, MPEG4, etc.) on video data for storage in the memory 510. Still further, the EDC 610 may include multiple encoders for encoding different types of data according to different data formats. For example, the EDC 610 may include an MP3 encoder for audio data and an MPEG encoder for video data.
(91) The EDC 610 may decode output from the memory 510. For example, the EDC 610 may perform MP3 decoding on audio data output from the memory 510. Alternatively, the EDC 610 may perform MPEG decoding (e.g., MPEG2, MPEG4, etc.) on video data output from the memory 510. Still further, the EDC 610 may include multiple decoders for decoding different types of data according to different data formats. For example, the EDC 610 may include an MP3 decoder for audio data and an MPEG decoder for video data.
(92) It will also be appreciated that EDC 610 may include only decoders. For example, already encoded data may be received by the EDC 610 and passed to the memory controller 520 and/or the memory 510.
(93) The EDC 610 may receive data for encoding, or receive already encoded data, via the interface 630. The interface 630 may conform to a known standard (e.g., firewire, USB, etc.). The interface 630 may also include more than one interface. For example, interface 630 may include a firewire interface, a USB interface, etc. Data from the memory 510 may also be output via the interface 630.
(94) The presentation components 620 may present data output from the memory, and/or decoded by the EDC 610, to a user. For example, the presentation components 620 may include a speaker jack for outputting audio data, a display screen for outputting video data, and/or etc.
