IPC: G11B27/02
Filed: 2002-07-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide a data processing device, a data processing method and a program, by which an editing time required to edit video data and audio data, for example is reduced.  <P>SOLUTION: AV (audio visual) data are edited in an editing process section 23, which is used to edit the data, in accordance with the command that instructs editing. On the other hand, discrimination is made by a controller 24 to determine whether the command is instructing a copying of the AV data or not. When the command is to instruct a copying of the data, AV data are asynchronously transferred between drivers 1<SB>i</SB>(where i=1, 2 and 3) that are copy origins and drivers 1<SB>j</SB>(where j=1, 2 and 3) that are destination for the copying. When the command instructs an editing other than the copying, the AV data are synchronously transferred between the drivers 1<SB>i</SB>which reproduce the AV data prior to the editing and the section 23 and between the drivers 1<SB>j</SB>which records the AV data after the editing and the section 23. The above is applicable to an editing device which is used to edit AV data.  <P>COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a method of continuously depositing the atomic layers of respective single-layer films of a one single-layer film thickness by respectively bringing a plurality of precursors into contact with the surface of a substrate at different temperatures. SOLUTION: The deposition method has a process step of chemically adsorbing at least a first layer of the one single-layer film thickness on the substrate by bringing the substrate into contact with the first precursor at the first temperature.

The temperature can be changed by adding or removing heat by a thermal temperature heat pump. The substrate temperature is changed from the first temperature to the second temperature. The second layer can be reacted with the first layer by heating the same to the third temperature higher than the second temperature.  The deposition method can also be made to have a process step of depositing the atomic layer of first species at a temperature nearly optimum for deposition of the first species on the substrate. The atomic layer of second species may be deposited at nearly the optimum temperature for deposition of the second species different from the optimum temperature of the first species on the first species.

Title: Variable internal voltage generator, semiconductor memory device, and voltage generating method
Inventor: KIM JAE-HOON
IPC: G11C5/14
Filed: 2002-08-12
Abstract: PROBLEM TO BE SOLVED: To provide an internal voltage generator for peripheral circuits of a bank, and a semiconductor memory device and a voltage generating method provided the generator. SOLUTION: A control section generates a control signal responding to a bank activation command enabling a memory bank and a bank activation signal. An internal voltage generating circuit receives a reference signal, and outputs internal voltage of the same level as the reference voltage responding to the control signal. The control signal is enabled when the bank activation command and the bank activation signal are enabled simultaneously. Also, the bank activation signal is generated responding to an bank address. By this constitution, as internal voltage is supplied to only peripheral circuits of a bank selected by a bank address, needless power consumption can be prevented, also, as magnitude of internal voltage can be adjusted, appropriate internal voltage can be supplied always.
