The chip, etched in 0.25-micron detail — state-of-the-art for graphics processors — fits 10 million transistors
The i1103 was manufactured on a 6-mask silicon-gate P-MOS process with 8 μm minimum features. The resulting product had a 2,400 μm2 memory cell size, a die size just under 10 mm2, and sold for around $21.
The announcement of 1M DRAM in 1984 began the era of megabytes.
The first commercial synchronous DRAM, the Samsung 16-Mbit KM48SL2000, employs a single-bank architecture that lets system designers easily transition from asynchronous to synchronous systems.
IIRC, The AVR core is 12,000 gates, and the megaAVR core is 20,000 gates. Each gate is 4 transistors. The chip is considerably larger since the memory uses quite a lot.
1st fully integrated chip set microprocessor
Initially the 'Complex Number Computer' performed only complex multiplication and division, but later a simple modification enabled it to add and subtract as well. It used about 400-450 binary relays, 6-8 panels, and ten multiposition, multipole relays called "crossbars" for temporary storage of numbers.
This wafer was made just last Friday... and it's the first monolithic 3D IC ever fabricated within a foundry
backplanes contain 230 cards, approximately 10,148 diodes, 1409 transistors, 5615 resistors, and 1674 capacitors
MuP21 has a 21-bit CPU core, a memory coprocessor, and a video coprocessor
F21 offers video I/O, analog I/O, serial network I/O, and a parallel I/O port on chip. F21 has a transistor count of about 15,000 vs about 7,000 for MuP21.
As of ORCONF, 2016, the ZipCPU used between 1286 and 4926 6-LUTs, depending upon how it is configured.
