CS

Chip Select pin

This is an input pin to make chips select. When CS is “H” level, device is in deselect

(standby) status and SO becomes High-Z. Inputs from other pins are ignored for this

time. When CS is “L” level, device is in select (active) status. CS has to be “L” level before

inputting op-code.

SCK

Serial Clock pin

This is a clock input pin to input/output serial data. SI is loaded synchronously to a rising

edge, SO is output synchronously to a falling edge.

SI

Serial Data Input pin

This is an input pin of serial data. This inputs op-code, address, and writing data.

SO

Serial Data Output pin

This is an output pin of serial data. Reading data of ReRAM memory cell array and status

register data are output. This is High-Z during standby.
