Abstract

An electronic organizer including a CPU, a key switch matrix, a LCD drive, a LCD, a power supply, a flash memory, and a SRAM, wherein the flash memory has a program storage zone for storing the system control program, and a personal data storage zone divided into a plurality of sub-data storage zones for storing different personal data; the SRAM has a system parameter storage zone for storing a plurality of system parameters, and a personal data working zone for registering data from the personal data storage zone of the flash memory; when the user selects the desired personal data from the flash memory through the key switch matrix, the CPU is driven to fetch the respective data from the flash memory and register the data in the personal data working zone of the SRAM for permitting the user to search or edit the data by means of the parameters in the system parameter storage zone of the SRAM; the registered data will not be sent from the personal data working zone of the SRAM back to the flash memory when the search is done, and will be sent from the personal data working zone of the SRAM back to the flash memory after when the data is edited.

Claims

1. An electronic organizer comprising:

a CPU (central processing unit) for controlling the operation of the organizer, a key switch means for inputting instructions and data into said CPU by an user, a display means driven to display data from said CPU, a display means drive controlled by said CPU to drive said display means in displaying data from said CPU, and a power supply for providing the organizer with the necessary working voltage, wherein a flash memory and a SRAM (static random access memory) are installed and connected to said CPU by a bus, said flash memory comprising a program storage zone for storing the system control program, and a personal data storage zone for storing personal data, said personal data storage zone being divided into a plurality of sub-data storage zones for storing different personal data, said SRAM comprising a system parameter storage zone for storing a plurality of system parameters, and a personal data working zone for registering data from said personal data storage zone of said flash memory,

wherein when the system control program of said flash memory is executed, said CPU is at the stand-by mode to wait for input instructions and data from said key switch means;

when the user selects the desired personal data from said flash memory through said key switch means, said CPU is driven to fetch the respective data from said flash memory and register the data in the personal data working zone of said SRAM for permitting the user to search or edit the data in the personal data working zone of said SRAM by means of the parameters in the system parameter storage zone of said SRAM;

the registered data will not be sent from the personal data working zone of said SRAM back to said flash memory when the search is done and will be sent from the personal data working zone of said SRAM back to said flash memory after when the data is edited.

2. The electronic organizer of claim 1 wherein the personal data storage zone of said flash memory comprises a plurality of sub-data storage zones for personal name card data, memorandum data, and schedule data.

3. The electronic organizer of claim 1 further comprising an IC card having a built-in flash memory for connection to said CPU.

4. The electronic organizer of claim 1 wherein said CPU is ASIC.
