Abstract: A non-volatile memory is erasable by page and equipped with a row redundancy mechanism. In the case of the detection of a defective row of the memory plane, the storing of the address of the row in a non-volatile register is carried out and a redundant row having a new address is assigned. In the case of an attempt to write to the defective row, a write to the redundant row is carried out. When writing to the redundant row, the new content of the redundant row is loaded into a volatile memory and, following an operation for writing to any other row of the memory plane, a re-loading of the new content of the redundant row into the volatile memory.

Abstract: A tunneling transistor is implemented in silicon, using a FinFET device architecture. The tunneling FinFET has a non-planar, vertical, structure that extends out from the surface of a doped drain formed in a silicon substrate. The vertical structure includes a lightly doped fin defined by a subtractive etch process, and a heavily-doped source formed on top of the fin by epitaxial growth. The drain and channel have similar polarity, which is opposite that of the source. A gate abuts the channel region, capacitively controlling current flow through the channel from opposite sides. Source, drain, and gate terminals are all electrically accessible via front side contacts formed after completion of the device. Fabrication of the tunneling FinFET is compatible with conventional CMOS manufacturing processes, including replacement metal gate and self-aligned contact processes. Low-power operation allows the tunneling FinFET to provide a high current density compared with conventional planar devices.

Abstract: Upstream burst transmit times are dynamically communicated to the transmit unit in grants issued over time and in any order. A critical parameter is when to trigger the operation to order the buffered data stream for transmission. If the ordering operation is triggered too soon, a later grant of an earlier burst transmit time may not be accounted for and the subsequent transmission could violate the transmission order rule. If the ordering operation is triggered too late, the decision to transmit a burst at an earlier burst transmit time may violate the margin rule. To address these concerns, a fetch offset time in advance of each granted burst transmit time is assigned. As each fetch offset time is sequentially reached, a next partial data portion of the buffered data stream is prepared for burst communication.
