Memory Sizes and Store Organisation
Vincent Walsh · 1985
In most computer literature the size of the processor’s memory is expressed in multiples of 2 10 (= 1024) which is given the abbreviation K. So, 65,536 memory locations are written as 64K: this means the addressing range is 64K. 32,768 gives a 32K addressing range, and so on. The memory K should not, therefore, be confused with the denary K: 1024 ≠ 1000.
