Abstract:
An oscillator according to the present invention reduces power consumption by enlarging the pulsewidth of an oscillator output pulse. Since this pulse disables an oscillator current source, the enlarged pulsewidth reduces the time the current source is enabled. When a first capacitor charges to at least a reference voltage, a differential amplifier produces a low level signal that is provided to a latch generating the output pulse. The low level signal controls the latch to produce and maintain a high level signal until the latch is triggered. The latch signal disables the current source, while enabling a transistor to transfer charge from the first capacitor to a second capacitor. When the second capacitor attains a sufficient voltage, the latch is triggered to produce a low level signal, thereby enlarging the pulsewidth of the output pulse. The low level signal enables the current source and facilitates discharge of the second capacitor.

Abstract:
The circuit has a data memory (52) to receive and store a data, and a write tree (56) to receive the data and produce a parity data. A parity memory (54) receives and holds the parity data. A read tree (58) receives the data from the data memory and thee parity data from the parity memory. The read tree also produces a display, whether an error is occurred in the data during storage within the data memory. Independent claims are also included for the following: (1) an application housing with an application chip and a evidently good chip (2) a memory device with a data memory (3) a method for detecting an error in a memory device (4) a method for manufacturing an application housing (5) a error correction method.
