PC MEMORY TYPES by Mind Map: PC MEMORY TYPES

1. Static RAM (SRAM)

1.1. Very fast memory

1.2. Very expensive memory

1.3. Very big memory

1.4. Often used in processor caches

1.4.1. L1

1.4.2. L2

1.4.3. L3

1.5. No refreshing but still volatile

2. Dynamic Random Access Memory (DRAM)

2.1. Dynamic

2.1.1. Needs constant refreshing

2.1.2. Data in memory disappears if not refresh

3. Synchronous DRAM (SDRAM)

3.1. Synchronous with common system clock

3.2. 133 MHz clock = PC133

4. Rambus DRAM (RDRAM)

4.1. Introduce with 400 MHz FSB Pentium 4

4.2. Licensed by Rambus, Inc

4.2.1. Rambus

4.2.2. Intel Partnership

4.3. Much faster than older SDRAM

4.4. Expensive compared to SDRAM

5. Double Data Rate (DDR) SDRAM

5.1. 2X data rate "ordinary" SDRAM

5.2. PC-1600

6. Double Data Rate 2 (DDR2) SDRAM

6.1. Enhance

6.1.1. Electrical interface

6.1.2. Buffers

6.1.3. Off-chip drivers

6.2. PC2-3200

7. Double Data Rate 3 (DDR3) SDRAM

7.1. 2X data rate DDR2

7.2. Larger chip capacities

7.3. PC3-6400
