The Alma Technologies SPI-MEM-CTRL core offers the interconnection between a host and an SPI Flash memory device. The SPI-MEM-CTRL supports Single, Dual Input, Dual Input/Output, Quad Output and Quad Input/Output SPI protocol accesses and optionally includes Boot and Execute On-The-Fly support.
The core automatically identifies a variety of serial flash memories and communicates with the attached device at the maximum possible bandwidth. Register accesses are used to insert access requests and read/write data into/out SPI-MEM-CTRL core. Communication with devices other than those automatically identified, is also feasible as the core can be programmed with the memory device parameters. The SPI-MEM-CTRL can read, write or erase any part of the memory.
The core is rigorously verified. A complete verification environment that helps designers verify the functionality and compliance of the core, and additional aids for system-level simulation are available.
