Welcome to Latest Memory News.

• You knew DRAM ,EDO,SDRAM what about DDR SDRAM, ESDRAM, ESDRAM-DDR there is also Direct RAMBUS
  

• Mitsubishi's Fourth-Gen 3D-RAM :Mitsubishi unwrapped a new video card frame buffer RAM called 3D-RAM4 that promises a 25 percent speed increase over current technology. The new 3D-RAM promises to support: a single cycle read from the pixel buffer which improves 2D graphics performance, color data expansion which transfers the data in a new 32-bit color data register into 256 bits of data in the DRAM array, dirty tag expansion, and write enhancement.
  

• Fujitsu Hopes On DDR DRAM :Fujitsu is ramping up production of its first Double-Data-Rate DRAM (DDR DRAM), which is expected to match the performance of Intel's Rambus-Direct/nDRAM technology, also known as SDRAM-II.
  
• ESDRAM Approved By Memory Committee: The Joint Electron Device Engineering Council memory committee has approved Enhanced Synchronous DRAM (ESDRAM) as a superset of SDRAM. Colorado Spring-based Enhanced Memory Systems won the approval of its ESDRAM spec as well as its Double Data Rate Enhanced SDRAM spec . EMS is preparing to sample a lot of ESDRAM that will hit 166MHz speeds. The small company has sold enhanced versions of DRAMS and EDO RAM for years, but expects ESDRAM to compete with the Direct RAMBUS technology currently backed by Intel. But ESDRAM and DDR ESDRAM has an advantage over RAMBUS, both are backward compatible with SDRAM and DDR SDRAM standards approved by the JEDEC. ESDRAM combines two 4Kbit 10ns SRAM page caches and two 8Mbit 22ns Fast DRAM banks on one circuit. The design is expected to greatly reduce memory latency.
  
• Hitachi Announces 1GB DRAM :Hitachi Semiconductor has created a 1GB RAM chip by conglomerating 36 256mb DRAM chips into a single oversized memory module. It would increase the capacity of today's largest chips by 400%, allowing massive cacheing of video and 3D data.
