    摘要: A technique to increase transfer rate of command and address signals via a given number of command and address pins in each of one or more integrated circuit memory devices during a clock cycle of a clock signal. In one example embodiment, the command and address signals are sent on both rising and falling edges of a clock cycle of a clock signal to increase the transfer rate and essentially reduce the number of required command and address pins in each integrated circuit memory device.

    摘要: A system and method for decoding command signals that includes a command decoder configured to generate internal control signals to perform an operation based on the command signals and an operating state. The same combination of command signals can request different commands depending on the operating state. A command is selected from a first set of operations according to the command signals when the memory system is in a first operating state and a command is selected from a second set of operations according to the command signals when the memory system is in a second operating state.

    摘要: Embodiments of the present invention provide electronic devices, memory devices and methods of driving an on-chip signal off a chip. In one such embodiment, an on-chip signal and a second signal complementary to the on-chip signal are generated and provided to the two inputs of a differential driver. One output of the differential driver circuitry is coupled to an externally-accessible output terminal of the package. The other output may be terminated off the chip, but within the package. By routing the output signal and a second complementary output through the package, crosstalk potentially caused by the output signal can be reduced. Simultaneous switching output noise may also be reduced through use of a current-steering differential driver topology. Signal symmetry may also improve, reducing inter-symbol interference.

    摘要: An apparatus and method for repairing a semiconductor memory device includes a first memory cell array, a first redundant cell array and a repair circuit configured to nonvolatilely store a first address designating at least one defective memory cell in the first memory cell array. A first volatile cache stores a first cached address corresponding to the first address designating the at least one defective memory cell. The repair circuit distributes the first address designating the at least one defective memory cell of the first memory cell array to the first volatile cache. Match circuitry substitutes at least one redundant memory cell from the first redundant cell array for the at least one defective memory cell in the first memory cell array when a first memory access corresponds to the first cached address.

    摘要: A cache memory system and method includes a DRAM having a plurality of banks, and it also includes 2 SRAMs each having a capacity that is equal to the capacity of each bank of the DRAM. In operation, data read from a bank of the DRAM are stored in one of the SRAMs so that repeated hits to that bank are cached by reading from the SRAM. In the event of a write to a bank that is being refreshed, the write data are stored in one of the SRAMs. After the refresh of the bank has been completed, the data stored in the SRAM are transferred to the DRAM bank. A subsequent read or write to a second DRAM bank undergoing refresh and occurring during the transfer of data from an SRAM to the DRAM is stored in either the second bank or the other SRAM.
