IPC: G11C11/403
Filed: 1995-06-23
Abstract: PURPOSE: To decrease the amount of power dissipation and to shorten the time required for mode transition from an auto-refresh mode to a self-refresh mode in DRAM. CONSTITUTION: A mode switching signal for an auto-refresh mode and self- refresh mode is inputted from a signal line 10. When the signal is the auto-mode, an access-settling-timing forming circuit 3 outputs RAS and CAS and instructs the refreshment to DRAM. At this timer the number of refreshments is counted in a concentrated refresh counter 6. When the above described signal becomes the self-mode, the counted value A of the concentrated refresh counter 6 is compared with the stored value B of a concentrated refresh-number register 7. When the counted value A is smaller than the snored value B, RAS and CAS are outputted from a concentrated refresh-timing circuit 5 so that the refreshment is performed at a short interval. When the counted value A becomes larger than one stored value B, the DRAM is set an the selt-refresh mode.

Filed: 1986-08-01
Abstract: PURPOSE:To improve a transfer margin by forming a projection assisting the transfer of a bubble placed at the tip of a cusp formed to the permalloy pattern overlapped part of an ion implantation region into the permalloy pattern. CONSTITUTION:A cusp 81 having a center line 31 in the same direction as the center line of the cusp of a good track is formed to the ion implanting region 51 where the permalloy patterns 71 of the permalloy transfer line 1 are overlapped and a projection 91 whose center line (axial line) crosses the tip of the cusp 81 and prolonged in a direction nearly orthogonal to the center line 31 of the cusp 81 is formed. Thus, the bubble transferred in the permalloy path 1 enters along the permalloy pattern 71 in the ion implanting region 51 from the tip of the cusp 81. Then the bubble placed at the tip of the outside of the cusp 81 with a driving magnetic field taken by 30 deg. is transferred in the inside of the ion implanting region 51 with a stable operation margin without phase lag. Thus, the margin deterioration at the connection of the permalloy transfer path and the ion implantation transfer path is avoided.
