摘要: A switching circuit for switching a bit line potential VBL of a DRAM to a power supply potential Vcc, an intermediate potential Vcc/2 or the ground potential GND is provided. In normal operation, the bit line potential VBL is set to Vcc/2. In a special write mode, Vcc or GND is applied to all the bit lines through an equalizer, a desired word line is raised to "H" level, and Vcc or GND is written to the storage nodes of all the memory cells connected to the word line. It is possible to write Vcc or GND even to the storage node of a memory cell which has been replaced by a redundant memory cell.

摘要: A chip is divided into at least four regions of two rows and two columns. In each region, memory array blocks are provided between corresponding first control circuits disposed in the column direction at a constant pitch. A column decoder is disposed adjacent to the first control circuit. Second control circuits are disposed corresponding to the first control circuits. The second control circuits excluding the second control circuit on the column decoder side are formed in the same pattern.

摘要: A substrate is exposed to a gas of reactive material and an oxidizing gas. The oxidizing gas includes an ozone gas. A laser light beam is applied to the substrate through the reactive material gas and the oxidizing gas. The laser light beam activates the oxidizing gas. The activated oxidizing gas reacts with the reactive material gas to form an oxide deposited on the substrate.
