| 20120170348 | Ferroelectric Memory Write-Back - A self-timed sense amplifier read buffer pulls down a pre-charged high global bit line, which then feeds data into a tri state write back buffer that is connected directly to the bit line. The bit line provides charge to a ferroelectric capacitor to write a logical “one” or “zero” while by-passing an isolator switch disposed between the sense amplifier and the ferroelectric capacitor. Because the sense amplifier uses grounded bit line sensing, the read buffer will not start pulling down the global bit line until after the sense amplifier signal amplification, which makes the timing of the control signal for this read buffer non-critical. The write-back buffer enable timing is also self-timed off of the sense amplifier. Therefore, the read data write-back to a ferroelectric memory cell is locally controlled and begins quickly after reading data from the ferroelectric memory cell, thereby allowing a quick cycle time. | 2012-07-05 |

The shunt switch also improves reliability of the ferroelectric memory device by ensuring that excess charge does not affect the reading of the ferroelectric capacitor during a read cycle. | 2012-07-05 |

| 20120170369 | NONVOLATILE MEMORY DEVICES - Nonvolatile memory devices including memory cell arrays with first bit line regions and common source tapping regions which are alternately disposed on a substrate along a direction, a page buffer including second bit line regions aligned with the first bit line regions and page buffer tapping regions aligned with the common source tapping regions, and a plurality of bit lines spaced apart from one another and extending to the second bit line regions from the first bit line regions. | 2012-07-05 |
| 20120170370 | NONVOLATILE MEMORY DEVICE AND NONVOLATILE MEMORY SYSTEM EMPLOYING SAME - A nonvolatile memory device comprises a memory cell array, a row selection circuit and a voltage generator. The memory cell array comprises a first dummy memory cell, a second dummy memory cell, and a NAND string comprising a plurality of memory cells coupled in series between a string selection transistor and a ground selection transistor through the first dummy memory cell and the second dummy memory cell. During a read-out operation mode, a dummy read-out voltage is applied to a first dummy wordline coupled to the first dummy memory cell, and to a second dummy wordline coupled to the second dummy memory cell. The dummy read-out voltage has a lower magnitude than a read-out voltage applied to an unselected memory cell during the read-out operation mode. | 2012-07-05 |
