Title: Non-volatile semiconductor memory device and manufacture thereof
Inventor: OJI HIROSHI
IPC: H01L27/105
Filed: 1992-01-30
Abstract: PURPOSE:To subminiaturize a peripheral circuit transistor and to enhance a memory cell transistor in write efficiency. CONSTITUTION:As the drain region of a memory cell transistor Tr11 is composed of a drain diffusion layer 18 and a P<-> diffusion layer 23 and very sharp in concentration gradient, the production of hot electrons is promoted to enhance the memory cell transistor Tr11 in write efficiency. As the source region of the memory cell transistor Tr11 is composed of a source diffusion layer 17 and an N<-> diffusion layer 22 and gentle in concentration gradient, the memory cell transistor Tr11 is improved in dielectric breakdown strength at erasure of data. The source and drain regions of a peripheral transistor Tr12 are of so-called LDD structure and gentle in concentration gradient, so that the production of hot electrons is restrained and the memory cell transistor Tr11 can be subminiaturized by lessening a gate in length.

Title: Method and device for recording speed discrimination of magnetic recording and reproducing device
Inventor: NISHIMURA KOICHI
IPC: G11B15/087
Filed: 1985-03-04
Abstract: PURPOSE:To reproduce a magnetic tape which is recorded at two different speeds without deteriorating the recorded picture quality, by delivering a reproduction mode switching signal when the dissidence signal has a cycle corresponding to a specific dissident state and also a malfunction preventing signal is delivered. CONSTITUTION:In case no coincidence is detected in a reproduction mode between the reproducing speed and the recording speed, both the 161st and 262nd dissidence detecting means detect the dissidence of both speeds at a time. Then a discriminating means 6 delivers a reproduction mode switching signal for automatic discrimination of distance between both speeds. In case a dissidence detecting circuit 5 delivers a signal equal to a dissidence signal owing to a tracking shift, etc. although coincidence is obtained between said both speeds, no malfunction preventing signal E is supplied to the means 6. Therefore the reproduction mode switching signal is not delivered from the means 6. This ensures the stable reproduction with no malfunction.
