Multiclet MCp0411100101 : Weekend die-shotMulticlet - basically is a superscalar processor (4-wide at present) with out-of-order execution. 100 Mhz clock, 180nm tech. node, designed in Russia.
Die size - 10.2x10.2 mm.
After metallization etch (warning, high-resolution image might kill your browser):
SRAM cell size - 21.28 µm2. So, each of 16 memory blocks contains 72 Kibit of SRAM. Apparently ECC codes are used (72,64). Total accessible memory - 128 KiB.
Autosynthesized standard cell logic:
Test areas were cut with the crystal (resolution test):
