Title: Semiconductor storage device
Inventor: NAKAYAMA HIDEO
IPC: G11C29/00
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To enhance an efficiency for applying stress during a burn-in process for a semiconductor storage device of a fixed pulse drive type. SOLUTION: A burn-in signal is held at an H level during a burn-in process. An internal clock input to an internal reference pulse generating circuit 12 is further input to a first NAND circuit 124 via first and second inverters 121, 122. An output from the first NAND circuit 124 is always maintained at the H level irrespective of the status of the internal clock, since the burn-in signal is at the H level. Thus, a second NAND circuit 125 serves only as an inverter for the internal clock to be input. As a result, an internal reference pulse can be generated as a signal obtained by delaying an internal clock having a sufficient pulse width by the second NAND clock 125 and a fourth inverter 126, and is output to a circuit that performs a synchronous operation in a memory.

Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To stably and easily measure a free-run frequency of a voltage controlled oscillator without being affected by spurious radiation or noise from the voltage controlled oscillator by providing a means that minimizes the gain of an ACC amplifier circuit with an external signal in the case of measuring the free-run frequency to the title circuit. SOLUTION: In the case of measuring a free-run frequency of a voltage controlled oscillator circuit 9, even when a chrominance signal input terminal 1 has no input, a 1st changeover circuit 14 is thrown to the position of 14b by a control signal to apply a 1st reference voltage to a control terminal of an ACC amplifier circuit 2 so as to minimize, a gain of the ACC amplifier circuit 2 at all times. Thus, in the case of intrusion of spurious radiation or noise to the ACC circuit 2 through a sneak path from the voltage controlled oscillator circuit 9 to a power supply or ground, the amplification of the spurious radiation or noise by the ACC amplifier circuit 2 is eliminated thereby preventing the output of a error voltage between the spurious radiation or noise and a chrominance subcarrier to the output.
