    Abstract: A process for the manufacturing of electronic devices, including memory cells, involving forming, on a substrate of semiconductor material, multilayer stacks including a floating gate region, an intermediate dielectric region, and a control gate region; forming a protective layer extending on top of the substrate and between the multilayer stacks and having a height at least equal to the multilayer stacks. The step of forming multilayer stacks includes the step of defining the control gate region on all sides so that each control gate region is completely separate from adjacent control gate regions. The protective layer isolates the multilayer stacks from each other at the sides. Word lines of metal extend above the protective layer and are in electrical contact with the gate regions.

    Abstract: A method is provided for optimizing a PRML (Partial Response Maximum Likelihood) receiving channel for mass memory data receiving systems comprising an input receiving channel, a receiver placed downstream of the channel, a detector connected in cascade to the receiver, and a summing node being input both the receiver output through a delay line, and the output from the detector through an impulsive filter. The method includes performing an indirect estimate of the noise strength by filtering out the error sequence, i.e. the output signal from the summing node, through a filter, and selecting either the output from the summing node or the output from the filter to obtain an optimization parameter for feedback to the receiving system.

    Abstract: A method (1110a;1110b) of refreshing an electrically erasable and programmable non-volatile memory (100) having a plurality of memory cells (Mhk) is proposed. The method includes the steps of: verifying (1106-1114; 1152-1162) whether a memory cell has drifted from a correct condition (i.e., a predetermined voltage and/or voltage range), and individually restoring (1116-1130) the correct condition of the memory cell if the result of the verification is positive.

    Abstract: An interface manages the exchange of information between a bus system and a memory during reading, according to a communication protocol. The interface has a protocol-decoding unit, which receives from outside commands and information for managing the reading and generates a wait-code enabling signal, and a wait-state generating unit, which is connected to the protocol-decoding unit and outputs wait codes upon receipt of the wait-code enabling signal. When the memory ends reading, as signaled by switching of a read-state signal, a wait-state disabling circuit generates and supplies an end-of-waiting control signal to the wait-state generating unit, which thus outputs an end-of-waiting code.

    Abstract: The reading timing device has a data-sensing stage, receiving a sensing-latch signal, and an output stage, including an output buffer and enabled at a first switching edge of a synchronization signal. A reading timing stage generates the sensing-latch signal not before a preset time interval from the first switching edge of the synchronization signal. Thereby, reading, in particular data-latching in the data-sensing stage, is temporarily separated from switching of the output buffers. This separation is obtained using the sync signal. Since the output buffers must switch in a preset time from the rising edge of the sync signal, the pulse of the sensing-latch signal is shifted after this time, and more precisely after the falling edge of the sync signal.

    Abstract translation: 读取定时装置具有数据感测级,接收感测锁存信号,以及输出级,包括输出缓冲器,并在同步信号的第一开关边沿使能。 读取定时阶段不是在从同步信号的第一切换边缘的预设时间间隔之前产生感测锁存信号。 因此,读取,特别是数据传感级中的数据锁存,暂时与输出缓冲器的切换分开。 使用同步信号获得该分离。 由于输出缓冲器必须在同步信号的上升沿的预设时间内切换,所以在此时间之后,更精确地在同步信号的下降沿之后移动感测锁存信号的脉冲。
