    摘要: A NAND flash memory bank having a plurality of bitlines of a memory array connected to a page buffer, where NAND cell strings connected to the same bitline are formed in at least two well sectors. At least one well sector can be selectively coupled to an erase voltage during an erase operation, such that unselected well sectors are inhibited from receiving the erase voltage. When the area of the well sectors decrease, a corresponding decrease in the capacitance of each well sector results. Accordingly, higher speed erasing of the NAND flash memory cells relative to a single well memory bank is obtained when the charge pump circuit drive capacity remains unchanged. Alternately, a constant erase speed corresponding to a single well memory bank is obtained by matching a well segment having a specific area to a charge pump with reduced drive capacity. A reduced drive capacity charge pump will occupy less semiconductor chip area, thereby reducing cost.

    摘要: A dual function memory device architecture compatible with asynchronous operation and synchronous serial operation. The dual function memory device architecture includes one set of physical ports having two different functional assignments. Coupled between the physical ports and core circuits of the memory device are asynchronous and synchronous input and output signal paths or circuits. The signal paths include shared or dedicated buffers coupled to the ports, asynchronous and synchronous command decoders, a network of switches, and a mode detector. The mode detector determines the operating mode of the dual function memory device from a port, and provides the appropriate switch selection signal. The network of switches routes the input or output signals through the asynchronous or synchronous circuits in response to the switch selection signal. The appropriate command decoder interprets the input signals and provides common control logic with the necessary signals for initiating the corresponding operation.

    摘要: Provided is a memory system that has a plurality of memory banks and a plurality of link controllers. For each memory bank, there is first switching logic for receiving output for each link controller, and for passing on the output of only one of the link controllers to the memory bank. For each link controller, there is second switching logic for receiving an output of each memory bank, and for passing on the output of only one of the memory banks to the link controller. According to an embodiment of the invention, there is switch controller logic for controlling operation of both the first switching logic and the second switching logic to prevent simultaneous or overlapping access by multiple link controllers to the same memory bank, and for preventing simultaneous or overlapping access to multiple banks by the same link controller.

    摘要: In a nonvolatile memory, less than a full block may be erased as one or more pages. A select voltage is applied through pass transistors to each of plural selected wordlines and an unselect voltage is applied through pass transistor to each of plural unselected wordlines of a selected block. A substrate voltage is applied to the substrate of the selected block. A common select voltage may be applied to each selected wordline and the common unselect voltage may be applied to each unselected wordline. Select and unselect voltages may be applied to any of the wordlines of a select block. A page erase verify operation may be applied to a block having plural erased pages and plural nonerased pages.

    摘要: A technique for serially coupling devices in a daisy chain cascading arrangement. Devices are coupled in a daisy chain cascade arrangement such that outputs of a first device are coupled to inputs of a second device later in the daisy chain to accommodate the transfer of information, such as data, address and command information, and control signals to the second device from the first device. The devices coupled in the daisy chain comprise a serial input (SI) and a serial output (SO). Information is input to a device via the SI. The information is output from the device via the SO. The SO of an earlier device in the daisy chain cascade is coupled to the SI of a device later in the daisy chain cascade. Information input to the earlier device via the device's SI is passed through the device and output from the device via the device's SO. The information is then transferred to the later device's SI via the connection from the earlier device's SO and the later device's SI.
