Abstract

A solid-state memory apparatus including a characteristic code holding device for holding a characteristic code representing characteristics of an internal circuit, a readout device for reading out the characteristic code held in the characteristic code holding device, and an output device for outputting the characteristic code read out by the readout device to an external device.

Claims

1. A memory apparatus comprising:

characteristic code holding means for holding a characteristic code representing characteristics of an internal circuit;

readout means for reading out the characteristic code held in said characteristic code holding means; and

output means for outputting the characteristic code read out by said readout means to an external device to adjust an operation condition of the external device according to the characteristics of said internal circuit.

2. An apparatus according to claim 1, wherein the characteristic code includes a memory capacity, a transfer speed and an image size.

3. An apparatus according to claim 1, wherein said characteristic code holding means is a memory device.

4. An apparatus according to claim 1, wherein said characteristic code holding means is a combinational logic circuit.

5. A memory apparatus comprising:

a) a memory device for storing information;

b) storing means for storing specification information of said memory device; and

c) control means for controlling said memory device and said storing means, said control means reading out specification information from said storing means and outputting the specification information to an external device to adjust an operation condition of the external device according to the specification information of said memory device.

6. An apparatus according to claim 5, wherein the specification information includes a capacity of said memory device, a data transfer speed and an image size.

7. An apparatus according to claim 5, wherein said storing means is another memory device.

8. An apparatus according to claim 5, wherein said control means is controlled by another apparatus.

9. An apparatus according to claim 8, wherein said other apparatus is a solid-state
