Virtual Si Museum /2101/ Electron Devices Time Line

my own view on the electron devices time line. The electron devices scaling: from a single vacuum tube, a BJT, TTL digital ICs to 68719476736 devices in a NAND flash memory card. If you have something else to add, just let me know:

REF:

1. Vacuum Tube GE 9-22 188-5
2. 2N2905A BJT - PNP, -60 V, -600 mA, 600 mW, TO-39
3. TTL 74F00 IC - 5V, quad 2-input NAND gate; series F (=fast) introduced in 1978
4. 64Gb NAND flash memory card
