Basic DRAM Operations. ACTIVATE Bring data from DRAM core into the row-buffer. READ/WRITE Perform read/write operations on the contents in the row-buffer. PRECHARGE Store data back to DRAM core (ACTIVATE discharges capacitors), put cells back at neutral voltage.

This paper discusses the functional design of a 32-bit DDR SDRAM controller and implementation of the design through the synthesis and physical design flow which form a part of ASIC Design Flow. This block level, semi-custom implementation is done using Synopsys Design Compiler and IC Compiler at 90nm technology node.
DDR3 SDRAM is a new generation of memory technology standard introduced by JEDEC, support multibank in parallel and open-page technology. On the basis of in-depth study of DDR3 timing...
Embedded systems that use double data rate memory (DDR) realize increased performance over traditional single data rate (SDR) memories. As the name implies, DDR enables two data transactions to occur within a single clock cycle without doubling the applied clock or without to doubling the size of the data bus.
