Embodiment Construction

[0020] The purpose of the present invention is to introduce a FLASH memory chip with multiple independently operable storage spaces to solve the cost increase caused by the online update of the startup program or application program, more PCB space occupation, resource waste, design difficulties, etc. question.

[0021] The present invention provides the following solutions: in combination with the attached figure 1 As shown, the storage space 102 of the FLASH memory chip can be partitioned and managed, and the control lines of each region are independent, so that the processor 101 can operate independently without any interference between them. It is equivalent to dividing several areas under the capacity of a chip (capacity is recorded as M), and the sum of the capacities of each area (represented by Bank) (respectively recorded as M1, M2...Mn) is equal to the capacity of the entire chip , that is M1+M2+...+Mn=M. M1, M2...Mn can be equal or unequal. Each FLASH space has ...

Abstract

The FLASH memory chip having a plurality of storage spaces capable of operating independently comprise a processor, storage spaces and data wires. It is characterized in that: the storage space of the chip is divided into multiple areas; each of the control wires in the data wires respectively connecting with each area is independently connected with the processor to operate independently. The invention solves the problem of raised cost, much PCB space occupation, resource waste and difficult design in realizing on-line renewing of starting program and application program.

Description

technical field [0001] The invention relates to a flash (FLASH) memory chip used in the field of circuit design, which has multiple storage spaces and operates on a certain space without affecting other storage spaces, that is, each storage space is relatively independent FLASH memory chips. Background technique [0002] The flash (FLASH) memory chip has the following characteristics: the data stored in it will remain unchanged in the case of power failure, the data can be erased by electricity, and multiple read and write operations are allowed. Therefore, in the field of circuit design, FLASH memory is often used to store startup programs (such as BOOT programs, BIOS programs, etc.) or other application programs required for power-on of the processor system. [0003] Some processor systems need to update the content in the FLASH memory chip that has been written into the initialization program or application program based on the requirements of dynamic update and online d...
