Abstract
A memory includes a read/write amplifier configured to retrieve read data from a memory array, and a neural network based preconditioning circuit configured to receive a read data signal according to the read data. A neural network of the preconditioning circuit is configured to precondition the read data signal based on a characteristic of a read data transmission path to provide a modified read data signal. The memory further includes an output driver configured to transmit the modified read data signal.
