Serial memory comprising means for protecting an extended memory array during a write operation |
摘要 |
The present invention relates to a memory on a silicon microchip, having a serial input/output, an integrated memory array addressable under N bits, and at least one register that is read accessible, after applying a command for reading the register to the memory. The memory stores a most significant address allocated to the memory within an extended memory array wherein the memory is incorporated or intended to be incorporated. A master memory signal is generated based on the most significant address allocated to the memory. A central processing unit executes a command for reading the register and supplies the content of the register to the serial input/output of the memory only if the memory is the master memory within the extended memory array. The memory includes slave memories whose operation depends upon the read/write status of the master memory.
