Abstract:
A semiconductor memory device has a burst write mode in which predetermined plural command signals are input through a plurality of command pads and a mask control operation in the burst write mode is performed in response to the command signals. Therefore, the mask control in burst write mode is increased in speed to give an improved data transfer rate.
Abstract:
A synchronous DRAM (SDRAM) or a fast cycle RAM (FCRAM) includes capacitors connected by switches to a signal wire. The switches are controlled to connect and disconnect the capacitors to the signal wire. In a test mode, the transmission time of a control signal is tested by connecting various combinations of the capacitors to the signal wire, and then measuring the signal timing. The signal timing of the memory device can be controlled by selecting which and how many of the capacitors are connected to the signal wire.

The present invention is aimed at providing a semiconductor memory device which performs a row-address pipe-line operation in accessing different row addresses so as to achieve high-speed access. The semiconductor memory device according to the present invention includes a plurality of sense-amplifiers which store data when the data is received via bit lines from memory cells corresponding to a selected word line, a column decoder which reads parallel data of a plurality of bits from selected sense amplifiers by simultaneously selecting a plurality of column gates in response to a column address, a data-conversion unit which converts the parallel data into serial data, and a precharge-signal-generation unit which generates an internal precharge signal a first delay-time period after generation of a row-access signal for selecting the selected word line so as to reset the bit lines and said plurality of sense-amplifiers.
Abstract:
An input circuit has an input buffer and a detection circuit. The input buffer receives an external signal and outputs an internal signal. The detection circuit detects whether or not the external signal is provided. The input buffer outputs the internal signal when an output of the detection circuit indicates that the external signal is provided. This arrangement shortens the lock-on time of an internal circuit (synchronous circuit).
Abstract:
A semiconductor memory device, such as a synchronous DRAM, receives external commands and an external clock signal via input buffers. The device generates internal clock signals having a slower frequency than the external clock signal and uses the internal clock signals to acquire the external command. This allows more than one external command to be acquired for each cycle of the external clock. The acquired external commands are provided to command decoders for decoding. A mask circuit is connected to the decoder circuits and inhibits the decoding circuits, except for a first one of the decoding circuits, from decoding the external commands for a predetermined time period, when the first decoder circuit is decoding the external commands.

Abstract:
A clock pulse generator generates a plurality of clock pulses which has different phases during one cycle of a reference clock signal supplied from the exterior. A timing setting circuit sets a latency, which is a number of clock cycles from a start of a read operation to an output of read data, at a number which is divisible by one n-th (n=2, 3, 4 . . . ) of a cycle of the reference clock signal and outputs latency information according to the set latency. An output controlling pulse switching circuit respectively outputs each of the clock pulses as a predetermined output controlling pulse in accordance with the latency information. In other words, a plurality of the output controlling pulses are switched according to the latency information. In synchronization with each of the output controlling pulses, a data outputting circuit sequentially and respectively converts parallel data, read from a plurality of memory cells stored with data, into serial data and respectively outputs the converted serial data during the predetermined period according to the latency. No matter what timing of the reference clock signal the latency might be set at, therefore, the serial data can be reliably outputted without switching the parallel data. The data are outputted at high speed because the parallel data need not be switched.
