    摘要: An apparatus, system, and method for controlling data transfer to an output port of a serial data link interface in a semiconductor memory is disclosed. In one example, a flash memory device may have multiple serial data links, multiple memory banks and control input ports that enable the memory device to transfer the serial data to a serial data output port of the memory device. In another example, a flash memory device may have a single serial data link, a single memory bank, a serial data input port, a control input port for receiving output enable signals. The flash memory devices may be cascaded in a daisy-chain configuration using echo signal lines to serially communicate between memory devices.

    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 dynamic random access memory device includes a plurality of memory subblocks. Each subblock has a plurality of wordlines whereto a plurality of data store cells are connected. Partial array self-refresh (PASR) configuration settings are independently made. In accordance with the PASR settings, the memory subblocks are addressed for refreshing. The PASR settings are made by a memory controller. Any kind of combinations of subblock addresses may be selected. Thus, the memory subblocks are fully independently refreshed. User selectable memory arrays for data retention provide effective memory control programming especially for low power mobile application.

    摘要: A plurality of memory devices of mixed type (e.g., DRAMs, SRAMs, MRAMs, and NAND-, NOR- and AND-type Flash memories) are serially interconnected. Each device has device type information on its device type. A specific device type (DT) and a device identifier (ID) contained in a serial input (SI) as a packet are fed to one device of the serial interconnection. The device determines whether the fed DT matches the DT of the device. In a case of match, a calculator included in the device performs calculation to generate an ID accompanying the fed DT for another device and the fed ID is latched in a register of the device. In a case of no-match, the ID generation is skipped and no ID is generated for another device. The DT is combined with the generated or the received ID depending on the device type match determination. The combined DT and ID is as a packet transferred to a next device. Such a device type match determination and ID generation or skip are performed in all devices of the serial interconnection. With reference to device type provided to the interconnected devices, IDs are sequentially generated. The SI containing the DT, the ID and an ID generation command is transmitted in a packet basis to a next device.

Each bank includes at least two memory planes having corresponding page buffers, where any number and combination of the memory planes are selectively accessed at the same time in response to configuration data and address data. The configuration data can be loaded into the memory device upon power up for a static page configuration of the bank, or the configuration data can be received with each command to allow for dynamic page configuration of the bank. By selectively adjusting a page size the memory bank, the block size is correspondingly adjusted.
