    • An apparatus for testing a unit comprising an internal processor coupled to a register by an internal bus. The internal processor is programmed so that it can execute an algorithm. When executed, the algorithm performs an operation on the unit. The register is for storing a state datum. The internal bus is used by the internal processor to access the state datum when the internal processor is executing the algorithm. The testing apparatus comprises an external processor disposed external to the unit and an interface and switch disposed on the unit. The interface is coupled to the internal and external processors and is for receiving a plurality of commands from the external processor. The commands include an internal processor command and an open trap command. If issued, the internal processor command causes the internal processor to execute the algorithm. The switch is coupled to the interface and coupled between the internal processor and the internal bus. If the interface receives the open trap command, the switch permits the external processor to access the state datum of the register.
    • 一种用于测试单元的装置,包括通过内部总线耦合到寄存器的内部处理器。 内部处理器被编程为可以执行一个算法。 执行时,算法对单元执行操作。 寄存器用于存储状态数据。 当内部处理器执行算法时,内部总线由内部处理器使用来访问状态数据。 测试装置包括设置在该单元外部的外部处理器和设置在该单元上的接口和开关。 该接口耦合到内部和外部处理器,并用于从外部处理器接收多个命令。 这些命令包括内部处理器命令和打开的陷阱命令。 如果发出内部处理器命令,内部处理器将执行该算法。 该开关耦合到接口并耦合在内部处理器和内部总线之间。 如果接口接收到打开的trap命令,则交换机允许外部处理器访问寄存器的状态数据。

    • Systems including a bit sequence program controller to program in sequence non-volatile memory cells in an array of programmable non-volatile memory cells. The bit sequence program controller determines the bits that require programming by comparing the bits of the program word with an erased logical state of the array of programmable non-volatile memory cells. The bit sequence program controller further indicates which non-volatile memory cells in a word of non-volatile memory cells in the array of non-volatile memory cells require programming to match the program word. The bit sequence program controller counts the number of the bits that require programming in the program word by counting the number of bits of the program word that are not in an erased logical state to determine when the programming should be completed.

    • A semiconductor flash EPROM/EEPROM device which includes a command port for receiving instruction on a data line and providing control signals to a memory for providing program and erase functions, a method to program and erase the memory. A program sequence is comprised of setting up a program command during a first write cycle, preforming a second write cycle to load address to address register and data to to a data register, programming during a program cycle and writing a program verify command during a third write cycle to verify the programmed data during a read cycle. An erase sequence is comprised of writing a setup erase command during a first write cycle, an erase command during a second write cycle providing the erasure during an erase cycle, writing the erase verify command during a third write cycle which also addresses the address of the memory and providing erase verification during a read cycle. Both the erase and program cycles provide for measured incremental erasing and programming.
