    Abstract: The memory system has a current source architecture that has a separate current source for each group in a block of memory. When a leaky cell is detected, a fuse between the current source and the leaky group of cells is blown and a spare group of memory is substituted for the leaky group of memory. The current source architecture can be used in a current source test mode or in a current force test mode. The current source test mode detects if there is a leaky group of memory. In the current force test mode, the architecture determines the amount of current required by each group of memory to retain data. This information is then used to apply the required amount of current to each group of memory for data retention.
