摘要： Address information representing failed elements in an array portion of a device is delivered. Respective fail address bit values are stored in a plurality of fuses. A signal associated with a respective value of a portion of a further address is received. When the signal is received, one of the fail address bit values is delivered from one of the fuses to a corresponding latch circuit. The latch circuit receives fail address bit values from at least two of the fuses. One of the fail address bit values is selected based on the value associated with the signal. The latch circuit is activated to deliver the fail address bit value.

摘要： A semiconductor dynamic random access memory (DRAM) 300 with a programmable memory refresh counter 345 is presented. The counter 345 permits the specification of portions of the DRAM 300 to be refreshed, saving power and time over DRAMs that refresh the entire memory. The counter 345 may be programmed with a wordline address at the beginning of a block of memory and subsequent refresh operations automatically increment or decrement the value in the counter. Additionally, blocks of the memory not being refreshed can be accessed (written or read), improving the utilization of the memory device.

摘要： A precharge command can be issued to a single bank or a precharge-all command can be issued to all banks of an integrated circuit memory device (e.g., DRAM circuit) at any time during normal operation of the device. Internal circuits are provided to decode the respective commands and send them to the different independent memory banks of the integrated circuit memory device. A local precharge control unit (or circuit) is present inside each of the memory banks that can receive and process the decoded precharge commands. If certain specified timing conditions are met, the local precharge control unit can issue and store a precharge request for a specific bank. The precharge request can be held back until all timing requirements are fulfilled. The precharge request can then be automatically executed.
