Title: Focus control method for triangle integrator imaging device
Inventor: LI BAI-CHI
IPC: H04N9/28
Filed: 2001-11-15
Granted: 2003-11-01
Abstract: There is provided a focus control method for triangle integrator imaging device. In the triangle integrator imaging device, the beam signal required to form the final image is generated by the summing signals obtained by the channels on the probe. Therefore, even though each channel includes the noise added by dynamic focusing, the image quality is not influenced by counteracting the noise after summing. In order to synchronize the delay variations of the corresponding channels on two sides of the probe, two values of the same magnitude and opposite signs are respectively added so that the noise is counteracted after summing. The same controller is responsible for the delay variations of these two channels. Therefore, the number of delay controllers in the system is reduced by half. With such a characteristic, the triangle integrator imaging device can complete the control of dynamic aperture size and eliminate the noise added by dynamic focusing, and further maintain an output of single bit.

Title: A non-volatile memory device having high speed page mode operation
Inventor: TSAO CHENG-CHUNG
IPC: G11C16/34
Filed: 2002-04-04
Granted: 2004-11-01
Abstract: A nonvolatile semiconductor memory includes a plurality of memory cells arranged in columns and rows, a plurality of word lines, a plurality of bit lines, a plurality of output buffers, a plurality of page latches 18L, and a plurality of quick current level translators (QCLT). Each QCLT is connected to and is shared by a plurality of bit lines (32 in the preferred embodiment) through a first column decoder 44/46U and is also connected to a plurality of page latches through a second column decoder 46L. Each page latch is connected to one corresponding output buffer through a third column decoder circuit 38/40/42. The page latches are grouped in a plurality of sub-pages. The QCLT performs high speed and high accuracy current-mode comparison and converts the result of comparison into binary codes. These codes are stored in Q-latches 36U-2. The QCLT functions as a current-mode analog-to-digital converter (ADC) which converts the memory cell current to binary codes. The data latched in Q-latches will be transferred to page latches 34 for reading out. The cell current sensing devices (QCLT) are separated from the data storage devices (page latches). Hence, the QCLT can perform current sensing operation while the page latch data are being clocked out simultaneously. Within the pitch of 32 bit lines, the QCLT can be designed to achieve high speed sensing, while each page latch has a pitch of 2 bit lines, and shared by two columns of memory cells. High speed sensing makes QCLT more appealing to multi-level cell products. Since multiple sensing iterations are required to determine which levels the cell current located between. Higher speed means less waiting time.

Abstract: A hardware-based random number generator is provided for incorporation within an integrated circuit. The random number generator includes a first variable frequency oscillator, a second variable frequency oscillator, and frequency variation logic. The first variable frequency oscillator generates a first oscillatory signal at a first frequency.

Bits of the random number are configured from samples of the first oscillatory signal taken at the second frequency. The frequency variation logic is coupled to the second variable frequency oscillator. The frequency variation logic generates a noise signal that directs the second variable frequency oscillator to vary the second frequency. The noise signal corresponds to parity of a third oscillatory signal and a fourth oscillatory signal, where the third and fourth oscillatory signals are asynchronous to each other and to the first and second oscillatory signals.
