U61000
East German memory microchip
U61000 was the first 1-Mbit DRAM microchip produced in the German Democratic Republic by Zentrum Mikroelektronik Dresden in September 1988 based on CMOS technology. size: 12.60 mm x 4.53 mm DRAM organisation: 1024k x 1 Bit access time: 100 ns - 120 ns The first step in the project was to develop the chip, this was called U61000-1. After the design and technology were optimized, the U61000-2.1 was created.
