Title: Dynamic ram
Inventor: SUGIBAYASHI NAOHIKO
IPC: G11C7/10
Filed: 1992-07-16
Abstract: PURPOSE:To output a lot of data from one block at high speed without increasing a chip area by drawing out a data line in the direction orthogonally intersecting with a sense amplifier array. CONSTITUTION:By drawing out the data line in the direction orthogonally intersecting with the sense amplifier array, the data can be outputted by the number of sense amplifier in maximum from one sense amplifier array. In such a case, since the data line inputs to the nonselective sense amplifier array as well, a first circuit 7 transferring only the data in a selective block is necessary. The sense amplifier array is selected by a reed switch signal RS. On the other hand, since current consumption is increased when the data is outputted to the nonselective data line in the selective block, a second circuit pulling up only a selective data line to the potential of VCC-VTN is necessitated.

Filed: 1984-09-11
Abstract: PURPOSE:To make the time required for bringing the oscillating frequency of a VCO to a normal condition shorter in the AFC system of a demodulator, by providing a DC biassing means after a frequency discriminating means. CONSTITUTION:A modulated input signal (a) is inputted in a frequency discriminating means 12 after it is converted at a frequency converting circuit 11. The output voltage of the discriminating circuit 12 is branched and inputted in a low-pass filter circuit 14 through a DC amplifier circuit 13. A DC biassing circuit 16, to which the output voltage (e') of the filter circuit 14 is supplied, inputs the output voltage (e') in a VCO15 by producing an output voltage (h) so as to stabilize the output signal (b) of the converting circuit 11. The output of the VCO15 is given to the converting circuit 11 as another input. Therefore, the time required for bringing the oscillating frequency of the VCO15 to a normal condition can be shortened, since the output voltage (h) of the biassing circuit 16 immediately after the power supply is made instantaneously rises.
