Title: Coding of information in integrated circuits
Inventor: PESSOLANO FRANCESCO
IPC: H01L23/522
Filed: 2003-08-06
Abstract: The present invention relates to a method for coding information in an electronic circuit and an electronic circuit for coding information, said circuit comprising at least two electrically coupled signal paths (X0, X1). The invention is based on the idea that cross-talk between two electrically coupled signal paths (X0, X1) can be utilized to perform logical computation. A signal is propagating on two signal paths (X0, X1) in the form of either rising or falling transitions. The relative delay between the transitions on the two paths (X0, X1) determines the logic value of the output signal (X) to be produced. If the signal on the first path (X0) propagates faster than the signal on the second path (X1), an output signal (X) having a first logic value is produced. If the signal on the second path (X1) propagates faster than the signal on the first path (X0), an output signal (X) having a second logic value is produced.

Title: Semiconductor memory
Inventor: SHINOZAKI NAOHARU
IPC: G11C11/406
Filed: 2002-11-06
Abstract: A refresh signal is outputted in response to a refresh request being generated at a specified period, and refresh operation is executed. The refresh operation is ended when an access request competes with the refresh request. Consequently, access operation corresponding to an access request can be started quickly and the access time can be shortened. The access time can be shortened further more by varying the ending time of the refresh operation depending on the timing for delivering the access request. Operational margin of the refresh operation can be evaluated in a short time by forming a test circuit for informing the state of the refresh operation to the outside. As a result, developing period of a semiconductor memory can be reduced.

Title: Method for transmitting data by means of a carrier current
Inventor: FRUHAUF JOSEPH

Abstract: The invention relates to a method for transmitting data over a carrier current using a frequency band. According to said method: the frequency band is divided into N sub-bands, N being a whole number higher than, or equal to, two; an OFDM (Orthogonal Frequency Division Multiplexing) technique is carried out on each of said sub-bands; and calculations are carried out based on each sub-band. The inventive method is characterised in that the calculations based on each sub-band are independent from the calculations based on the other sub- bands, and said sub-bands are dynamically activated and allocated. The invention also relates to modulation and demodulation devices for carrying out said method.
