摘要： 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.

摘要： A method and circuitry are described that permit one to utilize a partially functional integrated circuit memory. A memory array is segregated into separate blocks that can each be isolated to minimize the amount of the memory array rendered unusable by a defect. Circuitry is also provided to program memory cells within the array to one of at least three amounts of charge and thereby increase the amount of storage provided by the remaining functional blocks.

摘要： Synchronous address latching circuitry for a memory device having at least first and second banks of memory arrays is described. The latching circuitry has a master latch to receive and store an external address. A first slave latch is also included to receive and store the external address from the master latch if the external address belongs to the first bank and to provide the external address as a first address to the first bank. A second slave latch is included to receive and store the external address from the master latch if the external address belongs to the second bank and to provide the external address as a second address to the second bank.
