摘要: Provided is a memory device in which the decrease of the effective bandwidth caused by the refresh operation of the memory device has been solved, a memory controller of the memory device, and a memory system thereof. A memory device that is operated in response to a command from a memory controller has a plurality of banks that respectively have memory cores including memory cell arrays and decoders and are selected by bank addresses; and a control circuit, which, in response to a background refresh command, causes the memory cores within refresh target banks set by the memory controller to successively execute refresh operation a number of times corresponding to refresh burst length that is set by the memory controller, and, in response to a normal operation command, further causes the memory cores within banks other than the refresh target banks and selected by the bank addresses to execute normal memory operation corresponding to the normal operation command, during the refresh operation executed by the memory cores within the refresh target banks.

摘要: This invention provides an apparatus in which a time difference between an eternal clock signal and an internal clock signal is eliminated, and in which a high operation speed even at a high operation frequency is accomplished without causing erroneous circuit operations. A semiconductor integrated circuit device is equipped with a signal generator for generating an internal clock signal for determining an operation timing of an internal circuit from an external clock signal. The semiconductor integrated circuit device includes a delay unit for bringing an edge of the external clock signal into conformity with the edge of the internal clock signal by delaying the output of the signal generator by the time obtained by subtracting a time corresponding to a circuit delay of the signal generator from a time corresponding to some integral multiple of a 1/2 cycle of the external clock signal.
