The 8086/8088 has 20 address lines. It can access 220, or 1MB, or 1,048,576 bytes of memory.
The 8086/8088 has 20 address lines. It can access 220, or 1MB, or 1,048,576 bytes of memory.
The number of address lines needed to access N-KB is given by log2N Then the number of address lines needed to access 256KB of main memory will be log2256000=18 address lines.
You need 30 address lines to access 1G of memory. 230 = 1,073,741,824. log2 (1,073,741,824) = 30.
The number of memory locations that can be directly accessed in a RAM chip depends on its size and architecture. For example, a 1 GB RAM chip typically has 2^30 (1,073,741,824) memory locations if each location holds 1 byte. The total number of directly accessible locations is determined by the addressing scheme, which is usually defined by the number of address lines in the chip.
It refers to Memory Address since variable will never be a NUMBER it is Memory Address like an HexaDecimal Address of FFFFH. Eds
It takes 23 address lines to address 8 mb of memory.
The 8086/8088 microprocessor has a 20 bit address bus, so the number of memory locations it can address is 220 or 1,048,576.
The address of the last byte in a 512 mega byte memory, expressed as a decimal number, is 536,870,911.
In real mode addressing for x86 cpus, memory is addressed with pairs of a segment and offset. The offset is added to the segment address multiplied by 16 to yield a 20-bit (20 binary digits, in other words, from the number 0 to (2^20)-1=1,048,575) address that points to a specific byte (8-bit number) in memory. Real mode is different than protected mode (which is used by Windows 95+, Linux on x86, etc) in that there is no segment protection, no inherent multitasking support, and it is possible to directly access the BIOS interrupts. Note also that the 20-bit address number prevents more than one (1) megabyte of memory from being addressed at a time.
HI I am Ahtarva,The addressibility is how many bits does that particular processor or micro-controller's architecture use to specify the address of a memory location in the memory. For example if someone say that addressibility is 8 bit then your memory address contains 8 bits and at maximum you have 2^8 different memory locations (or say memory addresses in your device). Here 2^8 is called Address space.
it is decimal unsigned number system...
There are a number of people who have asked this same question. The Answer is still Random Access Memory
