SAFE SECURE BIT STORAGE WITH VALIDATION

A bit storage device, integrated circuit, and method are provided. The bit storage device comprises registers to store an actual value, an inverse value, a differential actual value, and a differential inverse value, a validation circuit including validation inputs coupled to outputs of the registers and including a validity output to provide a validity indication, and a write circuit including write circuit inputs coupled to the registers, the write circuit configured to cause, at a first clock edge, the first register to store the actual value and either the second register to store the inverse value or the fourth register to store the differential inverse value, and, at a second clock edge, the third register to store the differential actual value and the other of the second register and the fourth register to store to store the inverse value or the differential inverse value, respectively. 提供种位存储装置、集成电路以及方法。该位存储装置包括：寄存器，该寄存器用于存储实际值、相反值、差分实际值以及差分相反值；验证电路，该验证电路包括耦合到该寄存器的输出的验证输入且包括用于提供有效性指示的有效性输出；以及写入电路，该写入电
