Title (EN) PROGRAM UPDATING METHOD AND TERMINAL DEVICE
(FR) PROCEDE DE MISE A JOUR DE PROGRAMMES ET TERMINAL
(JA) プログラム更新方法および端末装置
Abstract: front page image
(EN)When updating a program stored in a rewritable non-volatile memory such as a flash ROM, a program portion in a block of the non-volatile memory containing the portion of the stored program to be updated is spread into an RAM and only the portion of the spread program to be updated is indicated from outside and updated. The block of the non-volatile memory is erased and the program portion updated in the RAM is again recorded in the erased block of the non-volatile memory.
(FR)Lors de la mise à jour d'un programme stocké dans une mémoire non volatile réenregistrable telle qu'une mémoire morte flash, une partie de programme d'un bloc de la mémoire non volatile contenant la partie du programme stocké à mettre à jour est propagée dans une mémoire vive et seule la partie du programme propagé à mettre à jour est indiqué depuis l'extérieur et mise à jour. Le bloc de la mémoire non volatile est effacé et la partie de programme mise à jour dans la mémoire vive est réenregistrée dans le bloc effacé de la mémoire non volatile.
(JA)本発明は、Flash ROM等の書換え可能な不揮発性メモリ内に格納されたプログラムを更新する際に、格納されているプログラムの更新が必要な部分が含まれている不揮発性メモリのブロック内のプログラム部分をRAMに展開し、展開したプログラム部分のうち更新が必要な部分のみを外部から指示し更新する。そして、不揮発性メモリの該当するブロックを消去しRAM内において更新したプログラム部分を再び不揮発性メモリの消去したブロックに記録するようにした。
