Abstract: PURPOSE: A CAM cell detecting circuit of a flash memory is provided to decrease the access time of a CAM cell by forming a sensing node of the CAM cell in a high impedance state. CONSTITUTION: When a CAM cell is erased, a potential of the first node becomes a ground level. At this time, because a CAMLATCON signal is a low signal, a PMOS transistor(P7) and an NMOS transistor(N8) are turned on. After a fixed time passes, the CAMLATCON signal becomes a high signal, the PMOS transistor(P7) and the NMOS transistor(N8) are turned off, and a high signal is latched at an inverter latch. The latched data is outputted through a READ terminal. At this time, the READ signal is a low signal on the occasion of a programmed CAM cell, and the READ signal is a high signal on the occasion of an erased CAM cell. Because an impedance at the first node(node1) is a high impedance and a voltage at the first node(node1) becomes a constant voltage, an access time of the CAM cell is decreased.

Title: Method for controlling amount of fuel to be injected during acceleration/deceleration in a motor vehicle having electronic fuel injection system
Inventor: CHOI BYEONG NAM
IPC: F02D41/30
Filed: 2000-03-30
Abstract: PURPOSE: A control method of fuel injection in acceleration and deceleration of a vehicle is provided to keep an ideal air-fuel efficiency regular in acceleration or deceleration of a vehicle without regard to characteristics of fuel variable depending on manufacturing companies, regions or seasonal factors. CONSTITUTION: A vehicle is decided(S1) in acceleration or deceleration. Acceleration or deceleration of a vehicle is decided from the amount of suction air input from a suction air sensor, engine RPM(Revolution Per Minute) and vehicle velocity. If the vehicle keeps accelerated or decelerated, the amount of fuel injection necessary for acceleration or deceleration is decided(S2). Herein, the amount of fuel injection for acceleration or deceleration is decided by the same method as the former technology. If the vehicle is not in acceleration or deceleration, the amount of fuel injection is decided(S3) depending on other driving conditions. Then, the amount of fuel injection is corrected(S4) according to a correction coefficient(C). The correction coefficient is for correcting changes in air-fuel efficiency caused by manufacturing companies as well as regional and seasonal factors. The corrected amount of fuel is injected into a cylinder from an injector. After that, the air-fuel efficiency(lambda) in the cylinder is detected(S5) with regular time intervals until the vehicle finishes acceleration or deceleration. The air-fuel efficiency is detected by an O2 sensor mounted at an exhaust system of a vehicle. The deviation between the detected air-fuel efficiency and ideal air-fuel efficiency(lambda-0) is calculated, and the average(A) of the deviation is obtained(S6). If the average is higher than a specific value(r), the air-fuel efficiency in the cylinder exceeds the ideal air-fuel efficiency. Thereby, the correction coefficient is corrected(S8), considering the average of the deviation. The corrected coefficient is saved in a memory of a control system to be used for correction of fuel injection in acceleration or deceleration. Therefore, the amount of fuel injection is controlled to make the air-fuel efficiency the almost same as the ideal air-fuel efficiency.
