—A 1.2 V 1 Gb mobile SDRAM, having 4 channels with 512 DQ pins has been developed with 50 nm technology. It exhibits 330.6 mW read operating power during 4 channel operation, achieving 12.8 GB/s data bandwidth. Test correlation techniques to verify functions through micro bumps and test pads have been developed. Block based dual period refresh scheme is(More)
Mobile DRAM is widely employed in portable electronic devices due to its feature of low power consumption. Recently, as the market trend renders integration of various features in one chip, mobile DRAM is required to have not only low power consumption but also high capacity and high speed. To attain these goals in mobile DRAM, we designed a 1Gb single data(More)
