In modern digital systems large capacity and data
transfer rate is required. Synchronous DRAM (SDRAM)
became the memory of choice due to its speed, burst access
and pipeline features. A Controller is required to provide proper
commands for SDRAM initialization, read/write accesses and
memory refresh. In semiconductor memories there are
chances of errors. To ensure reliable data storage, an error
correction and detection scheme is required. This paper
describes the architecture design and characterization of
SDRAM Controller IP core with built in Error Correcting
Codes (ECC) module which is vendor neutral. The design is
described using Verilog HDL, simulated using ModelSim
and prototyped in Altera® platform FPGA. Resource
utilization and power analysis was done using Altera® Quartus
II. Hardware test results are obtained from Signal Tap Logic
Analyzer.
