What is multi port memory?

Multiport memory is a memory that helps in providing more than one access port to separate processors or to separate parts of one processor. A bus can be used to achieve this kind of access. This mechanism applies to interconnected computers too.

What is DDR memory controller?

Double data rate memory Double data rate (DDR) memory controllers are used to drive DDR SDRAM, where data is transferred on both rising and falling edges of the system’s memory clock.

What is a Sdram controller?

Because synchronous dynamic RAM (SDRAM) has complex timing and signalling requirements, a memory controller is necessary to avoid having to deal with the nitty-gritty details when reading or writing to memory. Its job is to hide the complexity of things like row and column addressing, precharging, and refreshing.

How does dual-port RAM work?

Dual port memory provides a common memory accessible to both processors that can be used to share and transmit data and system status between the two processors. The DS1609 is a dual-port memory with 256 bytes of SRAM memory that is accessed via two separate 8-bit multiplexed address/data ports.

What is the advantage of multiport memory organization Mcq?

The advantage of the multi port memory organization is the high transfer rate that can be achieved because of the multiple paths between processors and memory. The disadvantage is that it requires expensive memory control logic and a large number of cables and connectors.

How many memory controllers does the motherboard have?

The memory controller acts as the middleman in these operations, ensuring that the proper information is retrieved from the right locations. Dual-channel memory controllers are used in some types of memory. On these, two memory controllers work in tandem.

What is SDRAM in laptop?

SDRAM (synchronous DRAM) is a generic name for various kinds of dynamic random access memory (DRAM) that are synchronized with the clock speed that the microprocessor is optimized for. This tends to increase the number of instructions that the processor can perform in a given time.

What is difference between dual port and two port memory?

two-port has one read port and one write port. dual-port has two ports that can be configured as read+read, write+write, read+write.

What is difference between single port RAM and Dual Port RAM?

single port RAM can be accessed at one address at one time, thus you can read/write only one memory cell during each clock cycle. Dual port RAM has ability to simultaneously read and write different memory cells at different addresses.

What are the drawbacks of multiport memory that cause to replace it with another multi processor type?

Disadvantage:-

  • It requires expensive memory control logic and a large number of cables and connectors.
  • It is only good for systems with small number of processors.
