A semiconductor memory device has a silicon substrate 10. A first embedded layer 11 is formed in the silicon substrate 10 under a p-well 18 in an area below a region where a drain 36 of a driver transistor 30 is located. The first embedded layer 11 makes a junction with the p-well 18. Also, the first embedded layer 11 is formed below an n-well 16 and contacts the n-well 16. When the drain 36 of the driver transistor 30 is at a voltage of 3V, &agr;-ray may pass through the p-well 18, the first embedded layer 11 and the silicon substrate 10. As a result, electron-hole pairs are cut. Due to the presence of the p-n junction that is formed by the p-well 18 and the first embedded layer 11, only electrons in the p-well 18 are drawn to the drain 36. As a result, a fall in the drain voltage of 3V is reduced. As a consequence, the device structure makes it difficult to destroy retained data.

A semiconductor memory device that steps up word lines, each of whose length is short enough to stay within one of the blocks that is formed by dividing a memory cell array into multiple blocks. The device includes multiple memory cells connected to pairs of bit lines and word lines at intersections of the pairs of bit lines and the word lines. Multiple memory cell array blocks are formed by dividing the region where the memory cells are arranged into blocks. A first step-up line is commonly used in stepping-up the word lines. A step-up circuit is constructed of a step-up capacitor, which is connected to the first step-up line and a switching transistor, which precharges the step-up capacitor. The semiconductor memory device also has a step-up control circuit that outputs a precharge control signal, which precharges the step-up capacitor by ON driving the switching transistor, and a step-up driving signal, which changes the potential of the negative terminal of the step-up capacitor of the step-up circuit. Further, a second step-up line is provided in each memory cell array block. During operation, a single memory cell array block is selected by a block selective circuit and a single word line is selected by row selective circuits. In this manner, the single selected word line within the single selected memory cell array block is stepped up by means of the first and second step-up lines.

Attempts have been made to increase the number of pins of packages accompanying the trend toward fabricating integrated circuits highly densely and in smaller sizes. The present invention provides technology for improving reliability in fabricating packages of the surface-mounted type that have increased number of pins. That is, when the packages are mounted on the wiring substrate, the lead pins that receive load from the axial direction exhibit bending strength which is smaller than the junction strength of solder at the junction portions. To achieve this object, the lead pins are made of a material having large resiliency such as a fiber-reinforced material, a transformation pseudo elastic material, an ultra-high tension material, or a heat-resistant ultra-high tension material.

A processing unit performs a method including controlling a reading-out of data from a first storage medium at a predetermined read-out data rate to produce inputted data, and controlling a compression of the inputted data to produce first compressed data of a first compressed format. The method includes controlling a storage of the first compressed data in a second storage medium at a faster writing data rate than the predetermined read-out data rate, controlling a reading-out of second compressed data of a second compressed format from the second storage medium, and controlling a decompression of the second compressed data to produce decompressed data. The method also includes controlling simultaneously the storage of the first compressed data in the second storage medium, the reading-out of the second compressed data from the second storage medium, and audibly reproducing the decompressed data. The first compressed format is different from the second compressed format.

An output signal SHS is secondarily amplified by a high-frequency amplifier AMP3 and an output signal SHR is secondarily amplified by an AMP4 for which high-frequency side amplitude reducing means is taken. In this case, the AMP4 has small gain of a high-frequency region and its output SHR-2 is reduced in amplitude. However, a high-frequency noise has a frequency higher than that of a carrier wave SH and the amplitude of a noise NzB becomes smaller. The other output signal SHS is directly amplified by the wideband amplifier AMP3. The width of an SHS-2 and the width of the SHR-2 are adjusted by amplitude adjusting means throughout the whole region and then mutually added by both signals addition amplifying means again so that the amplitude of the output signal SHS is adjusted to the SHR-2, and a predetermined threshold value is set to extract the noises.
