摘要： A device and method of reading a ferroelectric memory, including providing a ferroelectric memory including a ferroelectric memory cell, a charge integrator, and a bit line connecting the ferroelectric memory cell and the charge integrator. Pulses are applied to the ferroelectric memory cell, where each of the pulses are of a value lower than that which will destroy data stored in the memory cell. Output voltage values from the ferroelectric memory cell are accumulated by the charge integrator in response to each pulse. The output of the charge integrator may be read to determine whether the datum value stored in the memory cell is a logic high or low value. In one embodiment, the output of the charge integrator is read at a predetermined time after starting the pulses.

摘要： A ferroelectric non-volatile memory comprising: a plurality of memory cells each containing a ferroelectric FET, each of said ferroelectric FETs having a source, a drain, a substrate, and a gate. The FETs are arranged in an array comprising a plurality of rows and a plurality of columns. There are a plurality of row select lines, each associated with one of the rows of said ferroelectric FETs, and a plurality of column select lines, each associated with one of the columns of ferroelectric FETs. Each of the sources is directly electrically connected to its associated row select line, and each of the drains is directly electrically connected to its associated column select line. The source and substrate of each FET are also directly electrically connected. A memory cell is read by connecting its row select line to ground, and its column select line to a small voltage. All the gates, and the row select lines of non-selected cells are open or connected to a high resistance source. Thus, the current in the selected column select line and row select line is a measure of the state of the selected cell. Each FET is fabricated using a self-aligned process so that no portion of a source/drain underlies the gate.

摘要： An electromagnetic induction apparatus for power transfer may include a first portion and a second portion. The first portion has at least one loop of central coil is winded on the central magnetic core, and the second portion has at least one loop of toroidal core winded on the toroidal magnetic core. When the first portion is inserted into the second portion, the toroidal coil is located around an outside periphery of the central coil. Since the central coil and the toroidal coil are mutual inductance on the same magnetic core, the electromagnetic induction efficiency is improved, leading to enhancing more than 50% of the power transmitted rate.
