Abstract: An unused state detection circuit is disclosed that detects an unused state in a semiconductor circuit. A semiconductor circuit is “unused” when the unused state detection circuit has not been permanently cleared. When a semiconductor circuit is first powered up, the unused state detection circuit will detect that the semiconductor circuit has not previously been “used” and can automatically activate a boot up procedure or a testing procedure (or both). After the semiconductor circuit is used, the unused state detection circuit provides an indication that the semiconductor circuit is no longer unused. The unused state detection circuit uses the state of a dedicated non-volatile memory array or a dedicated region of the general non-volatile memory portion of the semiconductor circuit to detect whether the semiconductor circuit has been previously unused.

Abstract: An integrated circuit device has a processing unit, a memory management unit, and a memory. The memory management unit is interposed between the memory and the processing unit for controlling access to the memory by the processing unit in one of three modes. In a first mode, called the system mode, the processing unit can access a system program stored in the memory for controlling the resources of the integrated circuit device. In a second mode, called the kernel mode, the processing unit can access an operating system program stored in the memory for controlling the of the integrated circuit device, limited by the system program. Finally in a third mode, called the user mode, the processing unit can access an application program stored in the memory for controlling the resources of the integrated circuit device, limited by the operating system program.

Abstract: A method is provided for selecting a group of memory blocks in a flash memory device given their starting and ending addresses. The method compares the two addresses to determine the multi-block first bit location which is the most significant bit location where the starting and ending addresses have different bits. The method then generates a converted memory block address where bits more significant than the multi-block first bit location are the ending address bits and where bits less significant than, or equal in significance to, the multi-block first bit location are equal to a logic 1. The method also generates a converted complementary memory block address identical to the other converted address except that bits in the bit locations more significant than the multi-block first bit location are the complements of the ending address bits.
