Title: Memory cell,flash eeprom,method for erasing of memory cell and method for control of flash eeprom memory cell
Inventor: JIAN CHIEN
IPC: G11C17/00
Filed: 1995-06-27
Abstract: PURPOSE: To erase an EEPROM with low power consumption by applying required voltages, respectively, to a source region and a control gate thereby bringing a drain region and a substrate into floating state. CONSTITUTION: When a memory cell 212 in EEPROM is erased, +12V is applied to a source region 26' through a switch SWS and a control gate 40 is grounded through a switch SW-G. A first P type substrate 22 and a drain 24 are impeded through switches SW-snb, SW-D and brought into floating state. Consequently, electrons 60 stored in a gate 38 migrate to the region of source 26' through Fowler-Nordhem tunneling caused by a field established between the gate 40 and source 26' and the cell 26' is erased. In this regard, a substrate 22' is floated to reduce the source current and a charge pump for negative charge can be eliminated resulting in erasure of flash EEPROM with low power consumption.

IPC: G11B20/02
Filed: 1992-06-19
Abstract: PURPOSE:To preserve picture data with high resolution with an inexpensive picture filing system by converting a video signal with high picture quality into a video signal with low picture quality and storing the converted video signal CONSTITUTION:A slow scan converter 3 converts a video signal with high picture quality outputted from a SEM(scanning type electromicroscope) with high resolution into the video signal of the NTSC or PAL system. The converted composite video signal is fed to an optical disk 5, in which the signal is stored. The high picture quality video signal from the SEM 1 is fed to a high picture quality television receiver 4, in which the signal is monitored. Picture data stored in the optical disk 5 are fed to the television receiver 6 of conventional picture quality, in which the signal is regenerated or fed to a printer 7 being an output device, in which the signal is printed out. It is possible to store the signal onto a home use VTR or a floppy disk in place of the optical disk 5. Thus, the picture data are compressed to decrease the information quantity and the data are prevented with less storage capacity.

Title: Method for recording defect information on disk device
Inventor: UCHIDA MITSUJIROU
IPC: G11B20/10
Filed: 1986-07-08
Abstract: PURPOSE:To shorten gap processing time by recording plural skip controls showing the defective positions on tracks and skip control pointers to a home address part and a count part. CONSTITUTION:The skip controls SC0-SC6, the cell numbers CN,..., the flag bytes FLG,..., the key length KL and the data length DL are successively recorded on a recording format of a counting part. The flag byte FLG consists of an overflow record flag 10, a defective track flag 12, an alternate track flag 13, and a 4-bit skip control pointer 14. The controls SC0-SC6 store seven defective positions at maximum where the counting part is recorded in the order of the recording directions. Then the byte FLG stores the pointer 14 which points the skip control to be processed next. Thus the defect information on the disk recording plane can be decided at a high speed.
