Abstract:
1. A method for recording high-speed input data into a matrix of memory devices of a first type, said matrix including at least two memory devices per row and at least two memory devices per column, wherein the memory devices of a row are connected to a common bus and to each row of said matrix a separate common bus is assigned, and wherein said memory devices each are internally arranged in multiple pages to which pages input data can be written in a sequential manner, and wherein when writing into said first type memory devices defects may occur at different locations in said memory devices, said method comprising the steps: A) writing a first section of input data in a multiplexed manner, using said common buses, in the same current page of the memory devices, starting with the first column of memory devices, column by column, and writing this first section of input data also in a corresponding section of an additional memory device of a second type different from said first type; B) checking whether or not at least one defect in at least one memory device has occurred while writing said first section of input data into said current page of the memory devices; C) writing the following section of input data in a multiplexed manner, using said common buses, in the following page of the memory devices, starting with the first column of memory devices, column by column, D) checking whether or not at least one defect in at least one memory device has occurred while writing said following section of input data into said following page; E) continuing with steps C) and D) until all sections of input data have been written into said matrix of memory devices and into said additional memory device; F) copying input data stored in corresponding sets of pages of said matrix of memory devices, which sets include per set at least one defect in at least one memory device, to corresponding sets of pages in said matrix of memory devices which are not yet occupied with said input data, thereby taking input data of defect single pages not from said matrix of memory devices but from corresponding single page data stored in said additional memory device.
