Memory-expandable electronic equipment and memory expanding method

Abstract

The invention discloses a memory expanding method. The method comprises the following steps of: detecting whether a built-in expandable memory is newly inserted; if the built-in expandable memory is not newly inserted, performing storage and installation operation according to a default program of a processor; if the built-in expandable memory is newly inserted, judging whether the inserted built-in expandable memory is partitioned or not; if the built-in expandable memory is not partitioned, partitioning the built-in expandable memory into at least two subareas, wherein at least one subarea is used as a built-in expandable area for expanding a user area in the memory; and storing and installing files or application programs to the built-in expandable area. The invention also provides memory-expandable electronic equipment.

Description

technical field [0001] The invention relates to the field of electronic equipment with memory, in particular to the electronic equipment and expansion method capable of expanding the memory. Background technique [0002] Existing portable electronic products such as mobile phones, e-books, MP4, etc. all have their own storage units, that is, memory, which is a non-volatile memory, such as a flash memory. see figure 1 An electronic product 100 includes a processing unit 11 and a flash memory 12 connected to the processing unit 11 , the flash memory 12 is generally divided into two areas, including a system area 121 and a user area 122 . The system area 121 is used for storing system files, and the user area 122 is used for user's access to files, and the user has absolute authority to use it. [0003] However, since the storage capacity of the flash memory 12 is limited, correspondingly, the capacity of the user area 122 is also limited. When a user runs a certain program, ...

AI Technical Summary

Problems solved by technology

[0003] However, since the storage capacity of the flash memory 12 is limited, correspondingly, the capacity of the user area 122 is also limited. When the user runs a certain program, the phenomenon of insufficient memory often occurs.

This requires the user to install software, stored files, and pre-stored applications not to be too large. The above problems limit the expansion of the functions of the electronic product 100 by the manufacturer and the user, and reduce the user's experience in using the electronic device.
