Title: Semiconductor integrated circuit device
Inventor: KOYAMA YOSHIHISA
IPC: G11C29/00
Filed: 1984-10-24
Abstract: PURPOSE:To obtain a semiconductor integrated circuit which incorporates a memory circuit using a fuse means of high reliability, by short-circuiting the both ends of the fuse means to set the same potential at these ends after discriminating the presence/absence of the fusing of the fuse means and preventing an electric field of a high level produced at a minute cut gap. CONSTITUTION:The presence or absence of fusing is decided for a fuse means F by turning on or off a MOSFETQ2 according to a defective address signal a0 while the power supply voltage Vcc is supplied to an electrode P2. If the means F has no fusing, for example, this state of the means F is held by a storage action owing to a low level of the output (node N3) of a gate circuit G1. While the high-level signal of the output of an exclusive OR circuit EX is delayed through a delay circuit DL. Thus a node N5, i.e., the output of the circuit DL has a rise up to a high level with a delay to turn on a MOSFETQ7 which short-circuits substantially both ends of the means F. As a result, the potentials at both ends of the means F are set at approximately equal level.

Filed: 1982-12-20
Abstract: PURPOSE:To reduce the load on software and to speed up polling by executing polling in charge of hardware and tabling a flag in a register. CONSTITUTION:An address scanning circuit AS inputs the clock MPUCLK of a microprocessor and generates selection addresses ADDR for selecting input/output circuits I/O0-I/O7. Those I/O0-I/O7 incorporate address decoders and when an address set to one I/O coincides with a selection address ADDR, a flag F indicating the output of the I/O is outputted. This flag F is inputted to a shift register SFT and written in an internal register REG synchronously with the clock MPUCLK while shifted and converted from serial to parallel. At this time, a write pulse generating circuit WG generates write pulses. The processor sends the write pulses to the register REG, and consequently the load on the software is reduced and the polling is speeded up.
