JPH05135232A - Ic card for game - Google Patents

Abstract

PURPOSE:To set a condition that game data can not be rewritten without cleaning a game in an IC card for game enabling rewriting of the game data. CONSTITUTION:An address signal generated from the CPU of a game machine main body is transmitted through a connector 4 by an address signal line 5 in the IC card for game to an E<2>PROM 3 which stores the game data. The E<2>PROM 3 outputs the data corresponding to the address through a data line 6 to the game machine main body. A control circuit 2 judges the advisability of writing, and when the game are cleared, a clear signal is inputted from the E<2>PROM 3 through a clear signal line 9. The control circuit 2 receives the signal, and opens the gate of a writing control signal line 8, so that the data of the E<2>PROM 3 can be rewritten.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game IC card composed of a rewritable memory element,
In particular, it relates to setting conditions that allow rewriting of the data.

[0002]

2. Description of the Related Art In a conventional game IC card, a game stored in the card is displayed on a display such as a CRT for enjoyment, and the contents of the game can be easily rewritten as shown in FIG. Therefore, when I got tired of the game software I am currently playing, I took a game IC card to a department store or a toy store and paid a fee for rewriting the data to play different game data.

[0003]

However, in the above-mentioned conventional technique, if the game software is rewritten every time the user is bored with the game software currently being played, a rewriting fee for data is considerably incurred. Have.

Therefore, the present invention solves such a problem, and an object thereof is to provide that the game data cannot be rewritten unless a setting condition such as clearing the game is satisfied. .

[0005]

A game IC card of the present invention is provided with a connecting terminal portion connected to a game machine at an end portion of an IC card body, and is composed of a storage element capable of rewriting data. In the game IC card to be played, a condition is set regarding whether or not the game data can be rewritten.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a game IC showing an embodiment of the present invention.
It is a block diagram of a card.

Reference numeral 3 is an E ² PROM which is a memory element in which predetermined game data is stored and which can be erased and written.

Reference numeral 4 denotes a connector, which is electrically connected to the main body of the game machine (not shown).

When the address signal generated from the CPU of the game machine main body is transmitted to the E ² PROM 3 through the connector 4 through the address signal line 5 in the game IC card, the E ² PROM 3 outputs the data corresponding to the address. Output to the game machine main body via the data line 6.

The control circuit 2 judges whether writing is possible, and when the game is cleared, a clear signal is inputted from the E ² PROM 3 through the clear signal line 9. Upon receiving the signal, the control circuit 2 opens the gate of the write control signal line 8.

When the gate of the write control signal line 8 is opened, the data in the E ² PROM 3 can be rewritten.

In this embodiment, the game data is cleared as the setting condition for rewriting the data.
By using the clock function, it is possible to make it impossible to rewrite the game data for a certain period.

In addition, an E ² PROM 3 is used as a data memory.
However, it is needless to say that the present invention is not limited to this as long as it is an erasable and writable storage element.

[0014]

As described above, according to the present invention, a game I which is composed of a memory element in which data can be rewritten.
In C card, by setting the condition about whether or not the game data can be rewritten (clearing the game as an example), I am absorbed in the game to satisfy the setting condition, so I get tired of the game immediately and spend money on another game. This has the effect of reducing the need to submit and rewrite.
