SRAM density is moving along quite nicely, and it's becoming much more cost-effective. We're down from $200 for a 512x16 stick to about $60 for two 512Kx8 parts, and we expect to be paying under $10 each for them with the next generation of parts due soon. b) DRAM has the massive advantage that a DRAM memory cell is _very_ small. SRAM does not have this advantage. > Terry Lambert -- ]] Mike Smith, Software Engineer msmith@gsoft.com.au [[ ]] Genesis Software genesis@gsoft.com.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control.
