Patent EP-0326953-A2 (EP)
Inventor: KERTIS ROBERT A
IPC: G11C11/413
Filed: 1989-01-27
Abstract: A BiCMOS write-recovery method and circuit for recovering bit lines in a digital memory system provides approximately 1 nS recovery time and allows a 256K BiCMOS SRAM to achieve 10 nS access time. All bit lines in the memory system connected to a column not being read are held at a high potential, approximately equal to the upper power supply. During a write, one bit line is pulled low and its complementary bit line is clamped with a bipolar transistor to an intermediate potential, thereby preloading the complementary bit line. Following a write, the bit line that was pulled low is pulled up with a bipolar transistor to the intermediate voltage. Simultaneously, the bit line and the complementary bit line are shunted together, then returned to the high potential. Undesired bootstrap capacitance effects in the bipolar transistors are minimized by connecting a plurality of pull-up transistors in parallel, and by feeding the clamping transistors with low impedance drivers.

Abstract: An optical memory device comprises a cylindrically-shaped optical information recording medium (1) and at least one optical head (4) disposed around the information recording medium for irradiating information recording medium with a light spot (6) for recording or reproduction of information. The optical head has light spot moving means (20, 21) incorporated therein for the irradiation position of the light spot. The recording or reproduction of information is made by causing the light spot moving means to perform a tracking control so that the light spot follows a desired track in an area within a range of movement of the light spot by the light spot moving means (or an information recording zone) in a state in which a relative positional relationship between the optical head and the cylindrically-shaped information recording medium in a direction parallel to the direction of a rotation axis (10) of the information recording medium is fixed with the optical head being not moved. The device can be constructed so that the position of one of the optical head and the cylindrically-shaped information recording medium relative to the other in the direction parallel to the direction of the rotation axis of the information recording medium is mechanically moved, thereby making   it possible to turn an information recording zone (9) in the range of movement of the light spot by the light spot moving means into another information recording zone (13).
