|
|
Term
| This type of memory located within the CPU does not need to be refreshed. It employs a flip-flop circuit to hold a given electrical signal, making it more expensive to produce yet faster than other types of RAM. |
|
Definition
|
|
Term
| List four characteristics that distinguish SRAM from other types of RAM. |
|
Definition
Flip Flop
inverters
cross coupled
static |
|
|
Term
Determine if the statement is true or false. If false, correct the statement.
SRAM is slower than DRAM. |
|
Definition
|
|
Term
Determine if the statement is true or false.
DRAM uses fewer transistors than SRAM and thus occupies less space, however, it
requires an occasional refresh signal to prevent data loss. |
|

|
|
Term
| DRAM memory cells are composed of these two components. |

Definition
|
|
Term
| The level detector that measures the charge present in each DRAM cell is this type of device. |
|
Definition
|
|
Term
Circle the correct responses.
SRAM is considered dynamic / static because it holds an electrical signal and does not require refreshing. DRAM is considered dynamic / static because each of its cells slowly loses its charge, requiring them to be refr |
|
Definition
|
|
Term
This type of memory “weaves” together two cell banks of data. It is synchronized with the
system clock, and can send data in bursts to achieve high transfer speeds. Although it is not faster than DRAM, it is more efficient. |
|
Definition
|
|
Term
| SDRAM is synchronized with the system clock, thus attention should be paid to purchasing memory with the appropriate speed. The memory speed chosen must correspond to the system bus speed. A motherboard with a front side bus of 133 MHz would require this |

|
|
Term
Determine if the statement is true or false. If false, correct the statement.
SDRAM is currently one of the fastest memory types on the market. When working on the class project, “Build a Virtual PC,” selecting SDRAM is recommended. |
|
Definition
| False---its not faster, just more efficant |
|
|
Term
| This type of memory improves upon the original technology offered by SDRAM. Its name was derived from its ability to transfer data on both the rising and falling edges of the clock. It can transfer two words per clock cycle, compared with SDRAM’s transfer |

|
|
Term
Circle the correct answer.
DDR SDRAM has an intricate electrical configuration, and transfers data in a parallel / serial form over a wide, 64-bit data bus. |
|
Definition
|
|
Term
| This memory configuration addresses two identical memory sticks, effectively weaving the information together and transferring it over a 128-bit bus. |
|
Definition
|
|
Term
This is the second-generation release of DDR SDRAM. It improves upon the DDR SDRAM
standard by restructuring the methods for requesting and storing data, and by addressing heat issues. |

Definition
|
|
Term
| This type of system memory quad-pumps data over a narrow, 16- to 18-bit channel at high frequencies. |
|
Definition
|
|
Term
| The high data transfer rates of both DDR and RDRAM result in a lot of heat production. To keep these components cool, one of these devices may be attached to the module. |
