  1. RAM Main memory, “pembantuutama”, volatile

  2. SLOT RAM

  3. Tipe Modul RAM Desktop • SIMM • DIMM • RIMM • CRIMM Laptop • SODIMM • SORIMM

  4. EDO RAM • 1995 • 33-66 mhz • 72 pin kaki

  5. SDRAM • 1996-2001 • 100-133 MHZ • 168 PIN • PENTIUM I, II, III, IV awal • Syncron clock speed dgn proc

  6. DDR (Double Data Rate) • Clock speed 2x sdram • Megabyte/second (MBps) • Umumnya bandwidth64 bit, bisa Dual Chanel • PC3200=3200MBps transfer rate

  7. Single Chanel vs Dual Chanel

  8. ROM (Read Only Memory)

  9. Memory Timing (4-4-4-12) • Cas Latency (CL)=waktuuntuk request sampai send, • Ras to Cas Delay=waktuuntukmengaktifkanbarisdankolomdalam matrix data • RasPrecharge=waktuygdiperlukanuntukmematikansaluran data danmengaksesbaris lain dalam matrix • Cycle time=waktuygdiperlukan agar memory bisadiakseslagi (request data)

  10. CPU SOCKET

  11. BACKPANEL
