Abstract
MECANISMO DE REGISTRO APRESENTANDO áREA SOBRESSALENTE PARA GERENCIAMENTO DE DEFEITO E INFORMAçãO DO GERENCIAMENTO DE DEFEITO, E PROCESSO DE ALOCAçãO DE áREA SOBRESSALENTE E PROCESSO PARA GERENCIAR DEFEITOS São fornecidos um mecanismo de registro apresentando uma área sobressalente para gerenciamento de defeito e a informação de gerenciamento da área sobressalente, um processo de alocação de área sobressalente, e um processo de gerenciamento de defeito. Quando uma área sobressalente primária alocada para reposição por deslizamento e reposição linear mediante inicialização, e uma área sobressalente alocada para reposição linear após a inicialização são insuficientes, aloca-se uma área sobressalente suplementar. Os tamanhos das áreas sobressalentes suplementares e primárias são determinados pelo número de defeitos gerados mediante a inicialização. A informação quanto aos tamanhos das áreas sobressalentes, e a informação de estado remanescente representando o grau de utilização das áreas sobressalentes, são registradas, de modo que as áreas sobressalentes possam ser eficientemente gerenciadas. Ainda, no processo de gerenciamento de defeito, quando uma área que já tenha sido linearmente resposta é alocada como área sobressalente suplementar, os blocos defeituosos no interior da área sobressalente suplementar não são utilizados para reposição linear, e as entradas de uma lista de defeitos secundários (SDL) com respeito aos blocos defeituosos não são alteradas.REGISTRATION MECHANISM SHOWING SPARE AREA FOR DEFECT MANAGEMENT AND DEFECT MANAGEMENT INFORMATION, AND SPARE AREA ALLOCATION PROCESS AND PROCESS FOR MANAGING DEFECTS A registration mechanism is provided featuring a spare area for managing defect and area management information. spare, a spare area allocation process, and a defect management process. When a primary spare area allocated for sliding replacement and linear replacement upon initialization, and a spare area allocated for linear replacement after initialization are insufficient, an additional spare area is allocated. The sizes of the supplementary and primary spare areas are determined by the number of defects generated upon initialization. Information regarding the size of the spare areas, and the remaining status information representing the degree of utilization of the spare areas, are recorded, so that the spare areas can be efficiently managed. Also, in the defect management process, when an area that has already been linearly responded is allocated as a supplementary spare area, the defective blocks within the supplementary spare area are not used for linear replacement, and the entries in a list of secondary defects (SDL) with respect to defective blocks are not changed.
