A memory card includes a non-volatile memory; and a power management unit for receiving an external supply voltage to supply an operating voltage to the non-volatile memory. A mask signal generator is configured to generate a mask timing signal for masking the timing signal in accordance with the input data. The movable section is formed such that, during the electrical connection operation, it is arranged substantially on a surface side opposite the immovable section. The process chooses a value for the cluster number K. The latex-treated filler slurry improves filler retention, only slightly reduces sheet strength and improves sizing performance. The memory layer is limited to regions over the parts of the source region and of the drain region facing the channel and is embedded all around in oxide.
