Title: Semiconductor memory device
Inventor: HIRANO HIROSHIGE
IPC: G11C16/04
Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor memory device capable of realizing operation at a high speed and operation with a low power consumption by suppressing an increase in capacitance of a main bit line, at a connecting point between the main bit line and sub-bit lines, caused by addition of diffusion capacitances of drains of sub-bit line selection transistors. SOLUTION: A semiconductor memory device comprises a main bit line MBL0, sub-bit lines SBL00, SBL10 connected to the main bit line MBL0 at a connecting point CN00 respectively via sub-bit line selection transistors QS00, QS10, and word lines WL00-WL07, WL10-WL17 each connected to one of memory cells of the sub-bit lines SBL00, SBL10. The two sub-bit line selection transistors QS00, QS10 are connected to the main bit line MBL0 at the connecting point CN00, and thus diffusion capacitances of drains of the sub-bit line selection transistors QS00, QS10, which provide a large portion of a capacitance value of the main bit line MBL0, are reduced, thereby suppressing an increase in the capacitance of the main bit line MBL0.

IPC: B29C45/26
Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To improve mold release properties by fitting a mold release agent spraying nozzle to at least the movable side mold of a mold for molding a molding material and spraying a mold release agent toward the mold by the nozzle. SOLUTION: After mold opening in which angular pins 5 are extracted from slide cores 14, 14 respectively, nozzles 16, 17 which have been closed so far by the slide cores 14, 14 are opened completely with a mold ejected. Accordingly, even after the molding being removed from a mold 1, a mold release agent 18 is kept to be sprayed from the nozzles 16, 17 to the cavities 19 of the slide cores 14, 14 respectively. Since the mold release agent 18 is applied sufficiently even to corner parts, which are usually difficult to be coated with a mold release agent, can be coated enough with the agent 18 by the nozzles 16, 17, the mold release effect of the agent 18 improves. By fitting porous opened members such as porous bodies to the end parts of the nozzles 16, 17 as required, the mold release agent 18 can be atomized appropriately to improve spraying further.
