Memories & Memory Controllers

Altera^® FPGAs provide abundant on-chip internal SRAM memory resources, yet system bandwidth requirements often necessitate the use of large, fast off-chip memory devices. Memory controller IP solutions from Altera and our partners include licensable cores, reference designs and design examples. All are hardware-tested drop-in design blocks that greatly simplify the local interface to complex memory devices.
