1. MRAM Roadmap Proposal v.1.0 2001. 4. 23

2. We propose two categories of FAST MRAM and HIGH DENSITY MRAM. · The 1st FAST MRAM introduction of 256Mb should be pulled in 2003, while the 256Mb DRAM is near the end of life by its cost model. (chip size </= 60mm 2 ) · The 1st HIGH DENSITY MRAM introduction of 512Mb may be in 2003. Density · FAST MRAM : 4x density, 2-year cycle to 2007, then may follow DRAM density after 2007. · HIGH DENSITY MRAM : Going on 4x density, 2-year cycle (or, 8x density 3-year cycle) with multiple stacking layers Feature size (half pitch) · FAST MRAM : 2-year cycle to 2008, 3-year cycle after 2008, Following DRAM after 2008 · HIGH DENSITY MRAM : 2-year cycle through 2014 We propose two categories of FAST MRAM and HIGH DENSITY MRAM. · The 1st FAST MRAM introduction of 256Mb should be pulled in 2003, while the 256Mb DRAM is near the end of life by its cost model.
