Fanuc A20B-3900-0053 SRAM Memory Module. This 256k plug-in module fits directly to 16i, 18i, 20i and 21i series Fanuc Circuit Boards.  

Whilst SRAM memory is more expensive than DRAM, it is not only faster but also consumes less power (including in idle state). This makes it ideal for use when bandwidth or low power are primary factors in CNC automation production lines.

SRAM modules have three different states:

  • Standby - where the circuit is idle
  • Read - where data has been recalled for use
  • Write - where data is being written, i.e updating content 

This Fanuc A20B-3900-0053 SRAM Memory Module is available to buy in our online shop. Alternatively, you can call or email us to check availability of Fanuc boards. We have experienced engineers on hand to offer support with any problems you have.
