A high speed safety block assembly includes a first and second cheek plates with a sheave and axle installed between the cheek plates. The high voltage transfer circuit includes a first high voltage switch for transferring a high voltage generated within a chip to the outside of the chip according to a clock signal and a first control signal, and a second high voltage switch for transferring the high voltage generated outside the chip to the inside of the chip according to the clock signal and a second control signal. The control logic sends particular values to the activate allowed logic and the last column counter logic at the beginning of a read or write operation, such as a new command load value, a read count value, and a write count value. Reticle pattern data having data representing binding portions serving as light blocking portions is formed.
