Abstract

PURPOSE: A contents memory chip for storing the multimedia data is provided to manufacture the device storing the contents such as a music, an electronic book, a software and a movie cheaply by using a semiconductor. CONSTITUTION: An address line and a data line select a memory cell and are used to an interface outputting the data. The outputting value is divided by a ratio of the values of the loads(11,10). An expressing bit is set by the detection ability for the output level of the loads for the applying voltage(VCC). An outputting digit can express more than few hundreds bits according to the corresponding design. In case of expressing the data of 8 bits, the 256 gigabits data is stored in a size of a 1 gigabit DRAM. In case of expressing the data of 16 bits, the 64 terabits data is stored in a size of a 1 gigabit DRAM. In case that the multimedia data has the analog characteristic, the multimedia data is stored as an analog form after sampling the multimedia data by using the load(10).

Description

Contents Memory Chip for Multimedia Data Storage

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data storage device, and more particularly, to a method of storing data of several megabytes to tens of gigabytes or more in a coin sized package using a semiconductor.

As a current content storage device, a magnetic or optical device such as a diskette, a CD-ROM (FIG. 3), a mimi diskette (FIG. 3 (B)), a DVD-ROM, a cassette tape, or the like is used.

Such devices have been recognized to have advantages of low production cost and easy mass production and distribution for recording music, movies, text data and software data.

However, such a storage device can easily make illegal copying of contents such as software and music, and requires a high manufacturing technology, an expensive device, high power consumption, and high power to make a device for storing and reading a large amount of data. There is a limit to reducing the size.

In addition, a flash memory [Fig. 3 (c)] is used as a storage device using a semiconductor. The flash memory is a kind of EEPROM, which is composed of NAND or NOR gates, so that the memory cell is very large, which makes it difficult to increase the capacity.

The semiconductor memory that can be increased in capacity is ROM, which has a disadvantage in that it takes a long time for masking in a manufacturing process.

The present invention is to replace the existing optical or magnetic storage device content of music, electronic books, software, movies, etc. by using a semiconductor to solve the above problems is a method of cheaply manufacturing using a semiconductor. .

SUMMARY OF THE INVENTION The technical problem of the present invention is to store a large amount of information in a small sized device, and to read the data, which enables a simple and low power consumption to be driven without a separate device. Regardless, the standard process can be used, resulting in low cost, high reliability and durability.

Hereinafter, described in detail by the accompanying drawings as follows.

1A is a basic structure diagram of a content memory chip. The address line and data line are used for the interface for selecting memory cells and outputting data.

The structure of the memory cell can be configured as (b) or (c). (B) is to use a single cell to represent one digit, which is implemented as a simple passive element such as a resistor.

(C) is a method used to represent many values with one memory cell. The output value can be divided by the ratio of the values of the load 11 and the load 10, and the load 11 and the applied voltage VCC. The representation bit may be determined according to the detection performance of the decoder 12 with respect to the output level of the load 10. The output digit may represent data in a number of hundreds or more bits according to its design. In the case of representing 8 bits of data, 256 gigabytes of data can be stored in a size of about 1 gigabit DRAM, and in case of representing 16 bits of data, 64 terabits of data can be stored. When the multimedia data has an analog characteristic, the data sampled using the load 10 can be stored in an analog form.

The memory cell configuration method of the present invention differs from that of the MASK-ROM in that the ROM uses a binary data recording method by arranging a circuit connected to a broken circuit inside the chip at the intersection using the principle of a fuse. In the present invention, the passive element can be used to represent hundreds of bits of data in one cell as shown in (c).

In addition, the difference between DRAM, SRAM, EEPROM, etc. is different in the circuit configuration method, such as the cell equivalent circuit of FIG.

In the present invention, when a content manufacturer produces and distributes a large amount of media, the contents can be produced and distributed at a lower price than an optical storage device, and there is much less risk of loss in the distribution process or storage by the user. In the case of illegal copying, it costs a lot of money, making it impossible to produce in secret.

According to the present invention, since the memory device is a semiconductor, data can be read only by an electrical contact when data is read, and thus, a device such as a motor or a head is not required as in an optical or magnetic storage device. The device's small size makes it easy to apply to fixed and portable devices, and the interface can be as simple as RAM or flash memory. In terms of the data storage capability, a larger amount of data can be stored than an optical device, a magnetic storage device, or another nonvolatile semiconductor storage device.
