RAM System We have a RAM system with 3 2 K 3 2 RAM system that has capacity of four 3 2 - bit words.
RAM System
We have a RAM system with RAM system that has capacity of four bit words.
Determine:
i the required number of chips to design the RAM system.
ii the number of address line for RAM system and each chip.
Design bit memory
We have a total memory capacity of Mbytes utilising Kbyte SRAM chips. To allocate
this memory to the smallest address space, provide the array configuration of the chips on the
memory board displaying all necessary input and output signals. Then, illustrate how
the Memory Address Register MAR and Memory Buffer Register MBR are organised
and should support both byte and bit word access. The Memory Address Register MAR is
responsible for holding the memory address being accessed, while the Memory Buffer Register
MBR stores the data being read from or written to memory. Follow the steps for answering.
Step : Determine the number of SRAM chips required:
Number of SRAM chips required Total Capacity of Memory Size of each SRAM chip
Step : Organize the SRAM chips in an array configuration:
Step : Assign Input and Output Signals:
Address Lines:
Data Lines:
Byte Enable BE BE:
Read Enable RD: Signal to enable reading from memory.
Write Enable WR: Signal to enable writing to memory.
Output Enable OE: Signal to enable the output buffer.
Chip Enable CECE:
Step : Organization of Memory Address Register MAR and Memory Buffer Register
MBR:
Memory Address Register MAR:
Memory Buffer Register MBR:
Note: The connection of control signals RD WR to various
control and timing elements will depend on the specific design and implementation of
the memory system.help
