Title: Microcomputer lsi
Inventor: ISHIMURA NAOHITO
IPC: G06F9/30
Filed: 1991-09-24
Abstract: PURPOSE:To improve the degree of margin of the time required for input of data from the external in a microcomputer LSI. CONSTITUTION:A read control signal 121 which requests data read from the external to a microcomputer LSI 100 is directly inputted to the data hold indication input of a data holding circuit 111. Since the data hold indication input to the data holding circuit 111 is delayed by the output delay of the read control signal 121, the degree of margin of the data read time is improved by this output delay.

Abstract: PURPOSE:To enable the erasure of information every bit by arranging layers of light-absorbing materials which selectively indicate the significant absorption of different various wavelengths from those of optical pulses used for the recording and retrieval of information, adjoining an optical recording layer. CONSTITUTION:If the pulses of a laser beam (L) passing through an objective lens 5 are transmitted into an optical recording medium from a substrate side, a light-absorbing substance layer 2 is formed on a substrate 1. This light- absorbing substance can indicate the significant absorption of a wavelength lambda2 as shown by an absorption spectrum curve II. An optical recording layer 3 is formed on the light-absorbing substance layer 2. The material of this opeical recording layer 3 indicates properly significant light absorption and is transformed from a high crystallinity state to a low crystallinity state through heating and quenching. Conversely said material is transformed from a low crystallinity state to a high crystallinity state through heating and slow cooling. In addition, a protection coat 4 of metal oxides such as SiO2, Al2 and O3 is applied to the optical recording layer 3.
