caption_attribution_description: English: Integrated circuit die image of a STM32F103VGT6 ARM Cortex-M3 MCU (microcontroller) with 1 Mbyte Flash, 72 MHz CPU, motor control, USB and CAN. Die size of 5339x5188 µm. View is from a Scanning Electron Microscope looking at the 180 nanometre SRAM cells on the die.
context_page_description: Static random-access memory is a type of random-access memory that uses latching circuitry to store each bit. SRAM is volatile memory; data is lost when power is removed.
  The term static differentiates SRAM from DRAM which must be periodically refreshed. SRAM is faster and more expensive than DRAM; it is typically used for CPU cache while DRAM is used for a computer's main memory.
