PROBLEM TO BE SOLVED: To provide an apparatus and a method for stably transferring data when processing of a host computer executing a software routine of an ADSL modem is delayed in modem communication using the ADSL modem. SOLUTION: The invention relates to a method and an apparatus for buffering data samples in a software-based ADSL modem. The method includes the steps of receiving samples of a buffer and determining if the received samples of data will exceed the storage capacity of the buffer. Selected samples of data from the buffer are deleted or compressed in response to the storage capacity being exceeded. The selected samples of data that were deleted are then reconstituted or decompressed. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To make it possible to manufacture a bit transistor of a smaller geometric shape without using an advanced costly lithographic tool. SOLUTION: The strip of a semiconductor material (e.g. P-type silicon) is oxidized, and the strip of oxide obtained as a result is removed. Then, depressions are left on the upper frontal surface of the semiconductor material having a sidewall of steep slope. There is no significant damage by ion bombardment on the sidewall of steep slope. It is because these are formed by oxidation and not by performing reactive ion etching on the semiconductor material. Therefore, a high-quality tunnel oxide can be formed on the sidewall of steep slope. Next, a floating gate 124 is formed on the tunnel oxide, and the corresponding word line is formed on the floating gate. After that, a conductive region (e.g. N-type silicon) is formed inside the bottom of the depressions. Finally, several conductive regions 150 (e.g. N-type silicon) corresponding to the floating gate are formed at the upper part of the edge of the depressions. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a high reliability semiconductor memory device which can increase a drain breakdown voltage, while satisfying two contradictory requirements for enhancing programming efficiency by improving a short channel effect and reduction in drain contact resistance. SOLUTION: A low-concentration shallow impurity region 7a formed so as to align with a control panel, and a high-concentration deep impurity region 7b formed so as to align with a sidewall film 8 and formed at a concentration higher than that of the low-concentration shallow impurity region 7a are formed at a drain 7. The programing efficiency is thus improved by forming the low-concentration impurity region 7a at the drain, resulting in the improvement of a short-channel effect, and the contact resistance of the drain can be reduced by forming a drain contact hole formation region 70 at the high concentration deep impurity region 7b.

Abstract:
PROBLEM TO BE SOLVED: To easily and surely increase degree of integration of, particularly a semiconductor device by meeting both requirements of improving the reliability of fine content holes and the suppression of wiring delays. SOLUTION: A semiconductor device utilizes the fact that a threshold, at which it is considered that an abrupt change occurs in the degassing quantity from a hydrogen silses quioxane(HSQ) film 12, when the quantity of hygroscopic SiH contained in the HSQ film 12 fluctuates exists in the relation between the quantity SiH and the degassing quantity. More specifically, the linear defect which is considered to occur in an insulating film 13 formed on the HSQ film 12 due to the desorption of a hygroscopic component is suppressed by reducing the hygroscopic property of the HSQ film 12, by using the HSQ film 12 containing a relative quantity of SiH or an absolute quantity of H as one insulating layer of an interlayer insulating film.
