摘要： A semiconductor memory device capable of a further reduction in power consumption for refresh operation is provided. Cell arrays S0, S1 are divided into respective four blocks B0˜B3 and B10˜B13. In a normal read/write operation, by address data designating a word line, one of the cell arrays is selected, and also one block is selected in the selected cell array, and further one word line is selected in the selected block. In a refresh operation, one of the cell arrays is selected, and four blocks in the selected cell array are simultaneously refreshed. Namely, respective one word line is selected from each of the four blocks, and the selected word lines are refreshed, thereby to reduce a power comsumption as compared to when the plural cell arrays are refreshed.

摘要： Refresh of memory cells is performed periodically by a refresh timer, and collision between memory access and memory refresh is avoided. When memory access occurs, an F/F 163 is set by a one shot pulse from an OS circuit 161, a memory access request is inputted to a memory accessing pulse generator circuit 171 through a NOR gate 167, and a latch control signal LC and an enable signal REN are outputted. When a refresh request from the refresh timer is inputted to an AND gate 168 during the memory access, the output of the NOR gate 167 is at the “L” level, and the refresh request is blocked by the AND gate 168. Thereafter, at the time when the latch control signal LC is turned into the “L” level, F/Fs 163, 164 and 165 are reset, the output of the NOR gate 167 is turned into the “H” level, the refresh request is inputted to a refreshing pulse generator circuit 170, and a refresh enable signal RERF is outputted.

摘要： The present invention provides a semiconductor memory device capable of checking operation in the worst case in address combinations, and its manufacturing method. Specific data for test are written into a memory cell array 30. Then, a test signal TE1 is set “1” to set a device in a test mode. Refresh addresses for test are then stored in a data store circuit 51. A first address for test is applied to an address terminal 21, whereby a normal read or write operation is accomplished based on the first address for test. A second address for test is applied to the address terminal 21, whereby a refresh operation is accomplished based on the address for test, and subsequently another normal read or write operation is accomplished based on the second address for test. Data of the memory cell array 30 are checked to decide the presence or absence of any abnormality.

摘要： A cell core unit and its peripheral circuit are driven by a relatively low voltage power supply. A constant voltage that does not depend on the power supply voltage is provided as a boosted voltage (VBOOST) to be supplied to a control signal for a word line of the cell core unit. A sense amplifier amplifies a higher voltage level of a bit line to the power supply voltage. Then, a circuit for generating a signal for defining the transition timing and/or the pulse width of a control signal from the peripheral circuit to the cell core unit performs signal delay using a delay circuit having a characteristic in which a delay time thereof decreases with reduction of the provided power supply voltage.
