摘要： A field programmable gate array includes a logic blocks, switching elements for establishing a signal propagation path, and memory cells provided corresponding to the switching elements for storing data determining on and off states of corresponding switching elements. In this gate array, a supply voltage fed to a power input terminal is transmitted to power supply nodes of logic circuit blocks. A booster circuit boosts the supply voltage fed to the power input terminal and feeds the boosted voltage to power supply nodes of memory cells for programming a signal propagation path. A high-level signal potential of each memory cell is fed to the gate of an n-channel MOS transistor which functions as the switching element. The switching elements are disposed on signal lines and serve to interconnect the signal lines selectively to establish a signal propagation path. The current supply capability of the MOS transistors is enhanced to realize faster propagation of the signal, and any harmful influence of the threshold voltage exerted on the signal amplitude loss can be suppressed by a rise of the gate potential in each MOS transistor.

摘要： A neural network device includes internal data input lines, internal data output lines, coupling elements provided at the connections of the internal data input lines and the internal data output lines, word lines each for selecting one row of coupling elements. The coupling elements couple, with specific programmable coupling strengths, the associated internal data input lines to the associated internal data output lines.

摘要： A semiconductor memory device operable for reading and writing in a normal mode and in a test mode is divided into memory cell sections each having blocks of memory cells. Data bus lines are connected to the respective blocks, and switches interconnect data bus lines connected to blocks of the different sections. The switches are made conductive during reading and writing in the normal mode and during writing in the test mode, and nonconductive during reading in the test mode. Input data are applied onto the data bus lines connected to one of the blocks for writing in the blocks of the sections simultaneously during writing in the normal mode and in the test mode. In the normal mode, data are read out of the blocks of the sections through the data bus lines connected to the above-mentioned one of the blocks. In the test mode, the data are read out of the blocks of the sections through the data bus lines connected to the respective blocks.

摘要： A telescopic differential operational amplifier circuit for use in a pipelined A/D converter is provided with two auxiliary differential amplifiers connected to two cascode circuits, each including cascode-connected first to fourth transistors. During the sampling phase, first and second switches are turned on to apply a predetermined bias voltage to the gates of first and fourth transistors, and the input terminal of the differential operational amplifier circuit is set to a common mode voltage. During the hold phase, the first and second switches are turned off so that a voltage of each of the gates of the first and fourth transistors change to follow an input signal inputted via the input terminal with coupling capacitors operating as a level shifter of the input signal. Then the differential operational amplifier circuit performs push-pull operation operative only in a transconductance drive region, and is prevented from operating in a slewing region.
