Problems solved by technology

On the other hand, it is easy to increase the capacity of NAND type semiconductor memory, but it is difficult to increase the capacity of NOR type semiconductor memory
However, as the amount of frame data stored in the NAND type semiconductor memory increases, the management data to be stored in the NOR type semiconductor memory also increases.
Therefore, there is a problem that the storage capacity for storing management data is insufficient relative to the storage capacity for storing frame data.

Embodiment Construction

[0016] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0017] FIG. 1 is a block diagram showing a configuration of a semiconductor memory storage device according to an embodiment of the present invention. The packing unit 10 for a semiconductor memory storage device shown in FIG. 1 packs audio data including a plurality of variable-length frames. Then, the semiconductor memory storage device temporarily stores the packed audio data in the buffer unit 20 , and writes it into the storage unit 40 according to the write control of the control unit 30 . In addition, the semiconductor memory storage device reads out the audio data stored in the storage unit 40 in accordance with the readout control of the control unit 30 . Then, the semiconductor memory storage device temporarily stores the read audio data by the buffer unit 50 , and unpacks and outputs it by the unpacking unit 60 .

Abstract

A semiconductor memory storage apparatus includes a packetization unit receiving content data includes a plurality of variable-length frames, and adding management data showing frame data inherent information to frame data of each variable-length frame, and further, packetizing the content data storing the frame data and the management data in each fixed-length packet for every variable-length frame, a buffer temporarily storing the content data at a fixed-length packet unit in write / read operation of the content data packetized at the fixed-length packet unit, a storage unit using a non-volatile memory as an information storage medium, and storing the content data supplied from the buffer, and a controller writing / reading content data packetized at the fixed-length packet unit with respect to the storage unit at a fixed-length packet unit.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application is based on and claims the benefit of priority from a prior Japanese Patent Application No. 2007-205843 filed on Aug. 7, 2007, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a semiconductor memory storage device that stores content data and the like in a semiconductor memory, and more particularly, to a method for managing content data in the semiconductor memory. Background technique [0004] A storage device using a semiconductor memory as a recording medium is widely used for recording and reproducing information content such as content data, for example, which can be multiplexed at the same time by a plurality of channels or has high-speed random access. In particular, the semiconductor memory storage device has no working part, so the reliability is high. In addition, the storage capacity of the semiconductor memory stor...
