The Reason for the disregarding of the SRAM’s is ________
Explanation: The reason for the high cost of the SRAM is because of the usage of more number of transistors.
The disadvantage of DRAM over SRAM is/are _______
Explanation: This means that the cells wont hold their state indefinetly.
The reason for the cells to lose their state over time is
Explanation: Since capacitors are used the charge descipates over time.
The capacitors lose the charge over time due to
Explanation: The capacitor loses charge due to the backward current of the transistro and due to the small resistance.
_________ circuit is used to restore the capacitor value.
Explanation: The sense amplifier detects if the value is above or below the threshlod and then restores it.
To reduce the number of external connections reqiured, we make use of ______
Explanation: We multiplex the various address lines onto fewer pins.
The processor must take into account the delay in accessing the memory location, such memories are called ______
To get the row address of the required data ______ is enabled.
Explanation: This makes the contents of the row required refreshed.
In order to read multiple bytes of a row at the same time, we make use of ______
Explanation: The latch makes it easy to ready multiple bytes of data of the same row simulteneously by just giving the consecutive column address.
The block transfer capability of the DRAM is called ________
The difference between DRAM’s and SDRAM’s is/are ________
Explanation: The SDRAM’s make use of clock signals to synchronise their operation.
The difference in address and data connection between DRAM’s and SDRAM’s is
Explanation: The SDRAM uses buffered storage of address and data.
A _______ is used to restore the contents of the cells.
Explanation: The Counter helps to restore the charge on the capacitor
The mode register is used to
Explanation: The mode register is used to choose between burst mode or bit mode of operation.
In a SDRAM each row is refreshed every 64ms.
The time taken to transfer a word of data to or from the memory is called as ______
Explanation: The performance of the memory is measured by means of latency.
In SDRAM’s buffers are used to store data that is read or written.
Explanation: In SDRAm’s all the bytes of data to be read or written are stored in the buffer until the operation is complete.
The SDRAM performs operation on the _______
Explanation: The SDRAM’s are edge-triggered.
DDR SDRAM’s perform fster data transfer by
Explanation: By transfering data on both the edges the bandwidth is effectively doubled.
To improve the data retrieval rate
Explanation: The division of memory into two banks makes it easy to access two different words at each edge of the clock.
