Abstract
A memory device having a single or a plurality of memory chips includes a memory part (control register, SPD memory unit) inside each memory chip, which memory part stores control data concerning the memory chip. The memory device enables writing-in or readout of the control data stored on the memory part to be able to set any desired control data for each memory chip, and, when the memory device has the plurality of memory chips, enables separate use of each of the memory chips.
Claims16
A memory device including a single or a plurality of memory chips, comprising:
- each memory chip that has a memory part, which stores control data concerning the memory chip, inside thereof,
- wherein the control data stored in the memory part is allowed to be written in and read out.
A control method for a memory device including a single or a plurality of memory chips, the method comprising a step of writing in or reading out control data concerning each memory chip to or from a memory part storing the control data.
A control program for a memory device executed by a computer, the control program driving the computer to execute a step of writing in or reading out control data to or from a memory part of a memory chip.
A memory card including a single or a plurality of memory chips, comprising:
- each memory chip that has a memory part, which stores control data concerning the memory chip, inside thereof,
- wherein the control data stored in the memory part is allowed to be written in or read out.
A circuit board provided with a memory device including a single or a plurality of memory chips, comprising:
- each memory chip that has a memory part, which stores control data concerning the memory chip, inside thereof,
- wherein the control data stored in the memory part is allowed to be written in or read out.
