IPC: G11C11/409
Filed: 1988-01-27
Abstract: PURPOSE:To obtain an integrated circuit capable of performing fast readout by sensing a bit line by a sense amplifier small in driving capacity at the time of sensing and activating another sense amplifier just before connecting the bit line to an I/O line. CONSTITUTION:The gate voltage SE1 of a sense amplifier driving transistor TRQ11 is set an 'H' at a time when the information of the startup memory cell of a word line is read out to the bit line, and the sense amplifier at a first string small in driving capacity is activated, then, bit sensing is started. Next, the gate voltage SE2 of a transistor Q12 is set at the 'H' at a time when certain potential difference exists between BL and the inverse of BL, and a second sense amplifier string large in driving capacity is activated. At this time, the common source node potential of the sense amplifier is clamped, and the sensing of a '0' reading bit line is suppressed, however, since the sense amplifier is provided a large driving force, it is possible to extract the charge of the I/O line at high speed corresponding to the information of the bit line. Therefore, it is possible to accelerate total reading speed remarkably.

Title: Reference voltage source device
Inventor: YOSHIMURA KUNIHIKO
IPC: G05F3/24
Filed: 1980-02-08
Abstract: PURPOSE:To improve the temperature characteristics, by connecting the two enhancement transistors having different threshold voltage levels in series to each others and thus realizing an equal current driving. CONSTITUTION:The gate/drain of the enhancement transistor 32 having the threshold voltage VT2.gm term beta2 is short-circuited between the gate and the drain of the n-channel enhancement MOS transistor 31 having the threshold voltage VT1.gm term beta1. Then the voltage is applied between the other end 37 and the source of the transistor 31. The both transistors are held at the region of saturation by giving a bias to secure VT1<V35<=2VT1-VT2 (V35: voltage of terminal 35). Thus the output point voltage VO becomes as shown by an equation, and VO=VT1-VT2 is obtained if beta1=beta2 is satisfied. In other words, the dependance is put only to the threshold voltage of both transistors.
