Abstract
A memory device, such as an MRAM memory, includes a memory array with a plurality of bit cells. The memory array is configured to store trimming information and store user data. A sense amplifier is configured to read the trimming information from the memory array, and a trimming register is configured to receive the trimming information from the sense amplifier. The sense amplifier is configured to receive the trimming information from the trimming register so as to operate in a trimmed mode for reading the user data from the memory array.
