EET250 Unit 2 Assignment Chapter Review

Document Content and Description Below

25. The first type of RAM that was synchronized with the CPU clock was __B___. a. EDO b. SDRAM c. DDR d. Parity 26. Explain how you can tell the difference between SDRAM, DDR, DDR2, DDR3, and DDR ... 4. 27. PC-3200 memory runs at a system clock speed of _____ MHz and can handle a theoretical throughput of _____ bytes per second. 28. DDR had twice the throughput of SDRAM at the same system clock speed due to the ability to clock two words per clock cycle, one on the rising edge and one on the falling edge of the clock. DDR2 doubles the throughput of DDR by _____. a. Clock doubling the input/output circuits on the chips within the DDR2 module b. Doubling the width of the data bus from 32 bits to 64 bits c. Doubling the buffer size used by DDR d. Increasing the voltage used 29. DDR3 increased the throughput from that of DDR2 by _____. a. Clock doubling the input/output circuits on the chips within the DDR3 module b. Doubling the width of the data bus from 64 bits to 128 bits c. Doubling the buffer size from that used by DDR2 d. Increasing the voltage used [Show More]
