Abstract
(EN)
Provided by the present application is a method for preventing a code from being re-written, comprising: by means of a first control unit, detecting the read-write operation type of a current control signal sent by a time sequence controller; if the current control signal is a write operation signal, the first control unit sending the current control signal to a latch; determining by means of a second control unit whether the checksum of the current control signal in the latch is the same as a preset checksum; and if the checksum of the current control signal is the same as the preset checksum, the second control unit controlling the latch to send the current control signal to a register, thereby carrying out the write operation. Further provided by the present application is a memory.

La présente invention concerne un procédé permettant d'empêcher la réécriture d'un code consistant : au moyen d'une première unité de commande, à détecter le type d'opération de lecture-écriture d'un signal de commande actuel envoyé par un contrôleur de séquence temporelle ; si le signal de commande actuel est un signal d'opération d'écriture, la première unité de commande envoie le signal de commande actuel à un verrou ; à déterminer au moyen d'une seconde unité de commande si la somme de contrôle du signal de commande actuel dans le verrou est la même qu'une somme de contrôle prédéfinie ; et si la somme de contrôle du signal de commande actuel est la même que la somme de contrôle prédéfinie, la seconde unité de commande commande le verrou pour envoyer le signal de commande actuel à un registre, ce qui permet de mettre en œuvre l'opération d'écriture. La présente invention concerne en outre une mémoire.

本申请提供一种防止代码被改写的方法,通过第一控制单元检测时序控制器发送的当前控制信号的读写操作类型。若当前控制信号为写操作信号,则第一控制单元将当前控制信号发送至锁存器。通过第二控制单元判断锁存器内的当前控制信号的总和检验码是否与预设总和检验码相同。若当前控制信号的总和检验码与预设总和检验码相同,则第二控制单元控制所述锁存器将当前控制信号发送至寄存器,从而进行写操作。本申请还提供了一种存储器。
