IPC: G06F7/00
Filed: 1991-02-08
Abstract: PURPOSE:To reduce current consumption for reading operation, even if access time of a memory cell of which access time is slow is not considered and variation of access time actually varied is comparatively large depending on selected memory cells. CONSTITUTION:In operation for reading data of memory cells M1-M8, a state in which data is actually read out from memory cells M9-M12 as a discriminating bit is detected by a detecting circuit 11, current stopping circuits 13 and 14 are operated synchronizing with it, and sense amplifiers 6a-6c is made non- activation. Also, all word lines W1-W4 are forced to set to a low level, and all memory cells are controlled in non-selection state. Thereby, a stationary current flowing to a memory is stopped. Therefore, a stationary current flowing to a memory is stopped with fast timing when access time is fast, and stopped with slow timing when access time is slow, then current consumption is reduced in actual operation.

Abstract: PURPOSE: To eliminate the cleaving property of a semiconductor wafer composed of a single-crystal compound having a high cleaving property so as to reduce the cracking of the wafer which occurs in the manufacturing process of the wafer by forming a non-single crystal material section on the side face of the wafer including the corner section formed of the main surface and side face of the wafer. CONSTITUTION: The cleaving property of a semiconductor wafer 1 is eliminated from the side face of the wafer 1 by forming a non-single crystal material section 1b on the side face of the wafer 1 including the corner section formed of the main body and side face of the wafer 1. Consequently, even when a very small crack 7 (chip) occurs on the side face of the wafer 1 during the manufacturing process of a semiconductor laser, the crack 7 is prevented from developing across the wafer 1 along the crystal plane 8 of the wafer 1, because the side face has no cleaving property. Therefore, the cracking of the wafer 1 can be reduced remarkably.
