Circuit for refreshing memory cells in a dynamic memory has a refresh control circuit, a memory circuit, a setting circuit and a reset circuit

摘要

A refresh control circuit (3,4,7) triggers a memory cell field (1) to access memory cells (MC) in a dynamic memory for a refreshing routine. A first selector circuit (4) selects one of the MC. A memory circuit (2) stores register bits (2-1 to 2-n), each assigned to an MC. A setting circuit (6) sets each assigned register bit during access to each MC. A reset circuit (5) resets each register bit. An independent claim is also included for a method for refreshing memory cells in a dynamic memory.
