Abstract
An integrated circuit may include a memory controller that interfaces with memory that operates using a memory clock signal having repeating memory clock cycles. The memory controller may include controller circuitry that receives memory access requests and generates corresponding memory commands using a controller clock signal having repeating controller clock cycles. The controller circuitry may partition each controller clock cycle into time slots that are associated with respective memory clock cycles. Each generated memory command may require a corresponding number of memory clock cycles to fulfill using the memory. The controller circuitry may assign a time slot to each memory command while preventing conflicts with previously issued memory commands.
