Semiconductor memory device having a temporary memory for each of one or more memory banks each having several cells for storing data

摘要

The semiconductor memory device (10) has at least one, preferably at least two, memory banks (12). The or each memory bank has several memory cells for storing data. At least one temporary memory (14) is provided for temporarily storing data read out from at least one memory cell. One temporary memory is respectively associated with each memory bank. The data are preferably read out after a given number of time units. Independent claims also cover a method of operating the device.
