Abstract

"CARTãO DE MEMóRIA DE SEMICONDUTOR E PROGRAMA QUE PODE SER LIDO EM COMPUTADOR". A presente invenção refere-se a um cartão de memória de semi-condutor que não mais permite uma prática ilegal de aquisição de conteúdo de um arquivo apagado. Aqui, quando um evento de apagamento é gerado, um manipulador de apagamento dá uma prioridade a uma operação de anular - limpar de uma entrada de arquivo e uma FAT para um arquivo a ser apagado em relação a uma operação de anular - limpar para outros constituintes do arquivo. Uma operação de anular - limpar para uma entidade de arquivo do arquivo é distribuída para uma pluralidade de manipuladores de evento incluindo o manipulador de apagamento.
