Patent EP-0492943-A2 (EP)
Inventor: MAXEY JAY A JR
IPC: H03K3/037
Filed: 1991-12-17
Abstract: A synchronized pulsed look-ahead circuit (10 in FIGURE 1) effects look-ahead operations for a flip-flop (20). It includes a LAPP section (12) and a DATA sense and control section (14). To initiate a look-ahead operation, the LAPP section triggers in synchronism with the control edge of CLK, switching the LAPP line active and enabling the DATA sense and control section. While enabled, the DATA sense and control section receives DATA IN, and depending on its phase, provides the appropriate logic levels to the DATA output driver, which then provides the appropriate DATA OUT. When the flip-flop has latched the DATA and is ready to assume control of the DATA OUT line, i.e., after the associated propagation delay, the LAPP pulse is terminated and the DATA sense and control section is disabled, terminating the look-ahead operation.

Abstract: When the estimated vehicle speed is calculated based on the wheel speed of a wheel to which the brakes are applied or for which antilock brake control is in effect, there may be a significant difference between the actual and estimated vehicle speeds, and it will be difficult to apply accurate antilock brake control. The object of the present invention is therefore to provide for a vehicle having both driven and non-driven wheels, an estimated vehicle speed detection apparatus that can calculate an estimated vehicle speed close to the actual vehicle speed when the brakes are applied or antilock brake control is applied to any of the wheels. The estimated vehicle speed detection apparatus has a memory (VMEM) for storing the estimated vehicle speed at the time antilock brake control of any driven or non-driven wheel begins, or at the time when brake operation begins, and a calculator for calculating (#31-#37) the estimated vehicle speed by comparing the driven and non-driven wheel speeds and selecting the highest wheel speed where the driven wheel speed is also lower than the estimated vehicle speed stored in the memory (VMEM), and calculating (#38 or #39) the estimated vehicle speed based on the selected highest wheel speed during the period antilock brake control is applied to any driven or non-driven wheel or the brakes are applied.

Abstract: A circuit for accessing a column of memory cells in an array of memory cells includes a pair of drivers for activating bit lines for writing data into a selected cell in the column of cells. Each driver includes a bipolar transistor operated with current and voltage applied to a base terminal thereof by a pair of field-effect transistors (FETs) wherein one of the transistors effectively shorts the base terminal to an emitter terminal for elimination of current flow during a state of nonconduction, this FET being overridden by a second FET which applies base current during a state of conduction during writing of the cell. The second FET in each driver is activated by a column address signal applied to a drain terminal thereof, and by a data input signal applied to a gate terminal of the FET to provide for writing during concurrence of the two signals. In the presence of only the column access signal, two sense transistors in branches of a cascode circuit are rendered operative by the column access signal for reading a selected signal. In the absence of both the column access and the data input signals, a restore circuit equalizes voltages of the bit lines, and sets the voltages at a level established by the threshold of an FET having its gate terminal shorted to its drain terminal.

Abstract: To provide an efficient redundant architecture for a flash-erase- type nonvolatile semiconductor storage device, an array of memory cells 31 is physically divided into a data area 36 and a tag area 37 so that respective parts of the two areas share a word line 32 but can be separately erased en bloc. A data area and a tag area that share one word line constitute a single logical unit. In the logical unit, the tag area stores location information for defective memory cells in the corresponding data area. On the basis of this information, the system avoids the use of the defective memory cells. The defective memory cell information is programmed in a test step performed after chip manufacture and, at the same time, ECCs are generated for the defective memory cell information and written to the tag area. Furthermore, the system is informed of the invalidity of the data area that shares a word line with a tag area by writing predetermined data to the tag area. Even when the data area is erased en bloc, the tag area is not erased and the defective memory cell information is retained there.
