    摘要: According to one embodiment, a semiconductor memory device includes a memory array, an address counter, an address detecting circuit and a control circuit. The memory array has a plurality of memory cells arranged at crossing positions of word lines and bit lines. The address counter increments an address including a row address and a column address in synchronism with a clock to sequentially output the incremented addresses. The address detecting circuit detects an address previous to an address including a row address to which the row address is switched at the address output from the address counter to output a detection signal. The control circuit performs a precharging operation to the bit lines connected to the memory cells according to the detection signal output from the address detecting circuit.

    摘要: According to one embodiment, a semiconductor memory device includes a first memory, a second memory and a control circuit. The first memory includes a first bank number. The second memory includes a second bank number larger than the first bank number. The control circuit controls a precharge operation with respect to bit lines provided in the first and second memories. When performing, with respect to the first memory, a synchronous operation that is effected in synchronization with a clock, the control circuit changes over a second precharge operation to an operation time different from a first precharge operation during a period from the end of the initial first precharge operation to the start of the subsequent second precharge operation after receiving an address.
