Abstract: An advantageous write verify operation for bipolar memory devices is disclosed. The verify operation is performed under the same bias conditions as the write operation. Thus, the verify operation reduces disturb conditions caused when verify operation is performed in opposite bias to write operation. The advantageous write verify operation may be performed with control logic on source and bit lines. In another embodiment, the advantageous write operation is performed with mux coupled to control logic. The mux determines whether verify (0) or verify (1) operation should be performed based on data in a program latch. Moreover, the mux may select bias conditions for read operations based on a register bit. Trim circuits optionally provide guard banding and modify reference voltages for verify operations performed in opposite polarity to normal read operation.

Abstract: Methods, memory devices and systems are disclosed. In one embodiment, a non-volatile memory device receives command signals through the same input/output terminals that receive address signals and write data signals and transmit read data signals. The input/output terminals are connected to a multiplexer, which is responsive to a received mode control signal to couple the input/output terminals to either a command bus or an input/output bus. A latch in the memory device latches the command signals when the mode control signal causes the input/output terminals to be coupled to the input/output bus. As a result, the command signals continue to be applied to the command bus. When the mode control signal causes the input/output terminals to be coupled to the input/output bus, write data signals are clocked into the memory device and read data signals are clocked out of the memory device responsive to a received clock signal.
