U61000 was the first 1-mbit DRAM microchip produced by the German Democratic Republic in September 1988 based on CMOS technology.[1]

  • 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. The final version for production was called U61000-2.2.[2]
