As an embedded technology, designers integrate it as IP into their systems on <a href=\"https:\/\/www.weebit-nano.com\/definition\/chip\/\" target=\"_blank\" rel=\"noopener\">chip<\/a>s (<a href=\"https:\/\/www.weebit-nano.com\/definition\/system-on-a-chip-soc\/\" target=\"_blank\" rel=\"noopener\">SoC<\/a>s). ReRAM is highly scalable, enabling it to be used as an embedded technology at manufacturing processes below 28nm, where embedded <a href=\"https:\/\/www.weebit-nano.com\/definition\/flash\/\" target=\"_blank\" rel=\"noopener\">flash<\/a> can\u2019t scale. As a back-end-of-line (<a href=\"https:\/\/www.weebit-nano.com\/definition\/beol-memory\/\" target=\"_blank\" rel=\"noopener\">BEOL<\/a>) technology, ReRAM has an advantage over flash which is a front-end-of line (<a href=\"https:\/\/www.weebit-nano.com\/definition\/feol-front-end-of-line-memory\/\" target=\"_blank\" rel=\"noopener\">FEOL<\/a>) technology. With flash, designers must often make compromises with analog components and other devices integrated in the front end. ReRAM doesn\u2019t have this problem, and you can also adapt ReRAM once for a technology node and it works for all its variants. Weebit created its ReRAM based on the most common materials and equipment used in <a href=\"https:\/\/www.weebit-nano.com\/definition\/fab\/\" target=\"_blank\" rel=\"noopener\">fabs<\/a> today.

Applying successive positive and negative voltages to the electrodes causes the <a href=\"https:\/\/www.weebit-nano.com\/definition\/bit-cell\/\" target=\"_blank\" rel=\"noopener\">memory cell<\/a> to switch from a <a href=\"https:\/\/www.weebit-nano.com\/definition\/lrs-low-resistance-state\/\" target=\"_blank\" rel=\"noopener\">Low Resistive State<\/a> (LRS) state to a <a href=\"https:\/\/www.weebit-nano.com\/definition\/hrs-high-resistance-state\/\" target=\"_blank\" rel=\"noopener\">High Resistive State<\/a> (HRS), encoding binary information through either a 1 (<a href=\"https:\/\/www.weebit-nano.com\/definition\/lrs-low-resistance-state\/\" target=\"_blank\" rel=\"noopener\">LRS<\/a>) or a 0 (<a href=\"https:\/\/www.weebit-nano.com\/definition\/hrs-high-resistance-state\/\" target=\"_blank\" rel=\"noopener\">HRS<\/a>) data bit stored in the memory cell.
