20150091615 | Embedded Non-volatile Memory Circuit for Implementing Logic Functions Across Periods of Power Disruption - A circuit having an autonomous ferroelectric memory latch (AML) is disclosed. An AML characterized by an AML input, an AML output, a first AML power contact, a second AML power contact and an AML state, and a first switch in series with one of the AML input or the AML output. The switch is positioned to prevent the state of the AML from changing when power is provided between the first and second AML power contacts. In one aspect of the invention, the circuit could include a second switch in series with the other of the AML input or the AML output and a latch in series with the AML input or the AML output. The latch is positioned such that a direct path back does not exist between the AML output and the AML input. | 04-02-2015 |
20150016175 | CMOS Analog Memories Utilizing Ferroelectric Capacitors - A memory cell and memories constructed from that memory cell are disclosed. A memory according to the present invention includes a ferroelectric capacitor, a charge source and a read circuit. The charge source receives a data value to be stored in the ferroelectric capacitor. The charge source converts the data value to a remanent charge to be stored in the ferroelectric capacitor and causes that remanent charge to be stored in the ferroelectric capacitor. The read circuit determines a charge stored in the ferroelectric capacitor. The data value has more than three distinct possible states, and the determined charge has more than three determined values. The memory also includes a reset circuit that causes the ferroelectric capacitor to enter a predetermined known reference state of polarization. | 01-15-2015 |

20140247643 | Analog Memories Utilizing Ferroelectric Capacitors - A ferroelectric memory having a plurality of ferroelectric memory cells, each ferroelectric memory cell including a ferroelectric capacitor is disclosed. The ferroelectric memory includes read and write lines and a plurality of ferroelectric memory cell select buses, one select bus corresponding to each of the ferroelectric memory cells. Each of the ferroelectric memory cells includes first and second gates for connecting the ferroelectric memory cell to the read line and the write line, respectively, in response to signals on the ferroelectric memory cell select bus corresponding to that ferroelectric memory cell. A write circuit causes a charge to be stored in the ferroelectric capacitor of the ferroelectric memory cell currently connected to the write line, the charge having a value determined by a data value having at least three states. A read circuit measures the charge stored in the ferroelectric capacitor of the ferroelectric memory cell currently connected to the read line to generate an output value, the output value corresponding to one of the states. | 09-04-2014 |
