What is the size of each memory location in RAM?
One memory location stores 1 byte (8 bits). The basic storage unit for memory is 1 byte. If you need to store 4 bytes, and place the first byte at 0001, the last byte will be at 0004. That’s one byte at each of 0001, 0002, 0003, and 0004.
How does RAM addressing work?
the CPU puts a value on the address bus of the location it wants to read or write. the CPU sets the state of the read/write line to indicate which direction the data is to flow. the memory decoder decodes high-order address lines into a single chip select for the relevant device for that address.
How many address bits are required for a 1024 * 4 memory?
Number of bits required to address 4 bits in 1024 x 4 chip is 2.
How many address bits are needed to select all memory locations in the 14k 1 RAM?
Explanation: If your RAM is organized as 32 bit words, then you need 4096+16*2^4 or 4352 addresses, if for 64 bit words, 2048+16*2^4 or 2304 addresses. In a system each byte is addressed individually. There are 1024 bytes in one k byte.
What is the difference between memory access time and memory cycle time?
Access time: For random access memory, access time is the time it takes to perform a read or write operation i.e. time taken to address a memory plus to read / write from addressed memory location. Memory cycle time = access time plus transient time (any additional time required before a second access can commence).
