Abstract: A method and system of utilizing a memory array device contained within an integrated circuit within the printer device is provided in which data bits are written in a row format, thereby filling an N.times.M memory array device and then read in a column format. An N.times.M memory array device is employed such as a 32.times.32 bit memory array. During the reading phase, data from a computer is read by the memory device in a parallel fashion so that data is written sequentially a row of memory cells, such as B0W0, B1W0, B2W0 . . . etc. Once the memory array is loaded up, the writing phase is accomplished by performing a parallel dump wherein all of the memory cells of the first column are read together such that a column of memory cells, such as B0W0 to B0W31 is read first, a column of memory cells, such as B1W0 to B1W31 is read second, a column of memory cells B2W0 to B2W31 is read third etc. The N.times.M memory array device is read in a column format instead of the standard row format.

Abstract: A circuit generates complementary output signals which occur essentially simultaneously to each other. The circuit comprises three inverting and one non-inverting pairs of complementary transistors, typically field effect types. One of the inverting pairs provides the circuit inverted output. The output of the non-inverting pair is coupled to the output of another of the inverting pairs, which provide the circuit non-inverted output. In this manner, full Vss to Vcc output levels are achieved for substantially symmetrical output signals.

Abstract: A spare decoder provides for the substitution of a spare component for repair of a defective semiconductor chip. For example, a spare row or column of memory cells can be substituted for a defective row or column of a memory chip by fusing fusible links in the decoder. The present invention implements the decoder in CMOS technology. To minimize power consumption, means are included for preventing current flow in an unused spare without having to fuse a link.
