Abstract

PURPOSE:To enable a device to be operated for a long time, by designating the storage space of a semiconductor storage device as the mapping space of the medium storage space of a floppy disk device, and stopping feed to the floppy disk device while the mapping of the content of the floppy disk is performed to the storage space of the semiconductor storage device. CONSTITUTION:The medium storage space 11 of a floppy disk device 10 is formed in the same size (storage capacity) as the storage space 21 of a semiconductor 20. Immediately after a medium is set on the floppy disk 10, the content of the storage space 11 is transferred in a transfer direction 51, then it is mapped on the storage space 21. After completing a transfer, a power source switch 40 is turned off by a signal from a control device, thereby, the feed to the floppy disk device 10 is stopped. Afterwards, when an access to the floppy disk device 10 is required, the access to the semiconductor storage device 20 instead of the floppy disk device is performed, and the floppy disk device 10 is prevented from operating entirely.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to information equipment, and particularly to a floppy disk device for portable equipment.

[Conventional technology]

Conventionally, this type of portable information equipment generally uses a battery as a power supply device.

[Problem that the invention seeks to solve]

In the conventional portable information devices mentioned above, batteries have a limited power supply, and in order to make them heavy enough to be portable,
It was not possible to install a floppy disk device, which consumes a lot of power, and even if it were installed, the operating time would be shortened, which was a major restriction on use.

[Means for solving problems]

The information device of the present invention includes at least one flow 2P disk device, a semiconductor storage device having a storage capacity that is a predetermined times the storage capacity of the medium of the floppy disk device, and a power supply device that supplies power to the floppy disk device. and forming a storage space of the semiconductor storage device as a mapping space of the storage space of the floppy disk device medium, and performing a first transfer of transferring the storage contents of the floppy disk device medium to the semiconductor storage device at a predetermined time; At another predetermined time, a second transfer is performed in the opposite direction to the first transfer, and from immediately after the first transfer ends until before the second transfer starts, the power supply is transferred from the power supply to the floppy disk device. It has a control device that stops power supply.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing the configuration of an embodiment of information equipment of the present invention.

The information device 1 includes a floppy disk device 10, a semiconductor storage device 20, a power supply device 30, a power switch 40, and a control device (not shown).

FIG. 2 shows a floppy disk device 10 in this embodiment.
media storage space 11 and storage space 2 of the semiconductor storage device 20
1, the medium storage space II of the floppy disk device 10 has the same size and storage capacity as the storage space 21 of the semiconductor storage device 20.

Immediately after a medium is set in the floppy disk device 10, the contents of the storage space 11 are transferred in the transfer direction 51 and mapped to the storage space 21. When the transfer is completed, the power switch 40 is turned off by a control signal from the control device.
Power supply to the Florapy disc device IO is stopped.

After this, when it becomes necessary to access the floppy disk drive 10, the semiconductor storage device 20 is accessed instead, and the floppy disk drive 10 is not operated at all. When the processing related to the medium is completed, the control device turns on the power switch 40 again to start supplying power to the floppy disk device 10, and the contents of the storage space 21 are transferred in the transfer direction 52, and are transferred to the storage space 11. Overlaid.

FIG. 3 is a diagram showing another embodiment of the present invention, in which the storage space 12 of the floppy disk device 10 has 16 memory blocks 2.
In contrast, the memory space 22 of the semiconductor memory device 20 is composed of four memory blocks 60, and the size of the memory space 22 is only 1/4 of the memory space 12. In this case, the data transfer between the storage space 12 and the storage space 22 may be the same as a virtual storage process called segmentation, and since segmentation is already known, it will not be explained here. omitted.

FIG. 4 is a flowchart explaining the overall operation of this embodiment.

In response to an access request to the P-disk device 10 (step 71), it is checked whether the block exists in the storage space 22 (step 72), and if it exists, the block is immediately accessed from the storage space 22.
(step 80), if there is not, turn on the power switch 40 (step 73), check whether there is an empty block in the storage space 22 (step 74), and if there is, transfer the contents of the block in the storage space 12 to the storage room 1. ' Transfer to a free block in J122 (step 78), if there is no block, select a block to be swapped from the storage space 22 (step 75), transfer the contents of the selected block to a predetermined block in the storage space 12 (step 78), The contents of the block No. 12 are transferred to the selected block of the storage space 22 (step 77), the power switch 40 is turned off (step 78), and the process proceeds to step 80.

In the present invention, the size ratio of the storage space 12 and the storage space 22 is 4.
It goes without saying that this is not limited to case 1, and although it was not specifically mentioned in the explanation of the above embodiment, when there is no need to access the floppy disk device IO, the power switch 40 is turned off. Needless to say, it should be controlled so that it stays the same.

〔Effect of the invention〕

As explained above, the present invention provides a semiconductor memory device,
By making the storage space of the semiconductor storage device a mapping space of the storage space of the floppy disk device medium, and stopping power supply to the floppy disk device while the contents of the floppy disk device are being mapped to the storage space of the semiconductor storage device, This has the effect of reducing battery power consumption and allowing portable information and m devices to operate for long periods of time.
