Analog Devices / Maxim Integrated DS2431 1024位元1-wire®EEPROM
Maxim DS2431是1024位元1-Wire®EEPROM晶片，分為4個記憶體頁，每頁256位元。資料寫入8字節便籖簿，確認，然後複製到EEPROM記憶體。Maxim IC DS2431的4個記憶體頁能個別設為寫入保護，或放入EPROM模擬模式，此模式內的位元只能從a 1至a 0狀態間轉換。DS2431 EEPROM晶片透過單一導線1-wire匯排流進行通訊。該通訊遵從標準1-wire協議。各DS2431設備擁有自己不可變更的單一64位元ROM註冊碼，該註冊碼由工廠用鐳射方法印到晶片上。註冊碼用來在多點連結1-wire網路環境中的設備定位。這些Maxim EEPROM設備專為多種不同應用而設計，其中包括配件/PCB辨識、醫療傳感器校驗資料儲存及類比傳感器校驗
