Connect available memory address lines of memory chips with those of the microprocessor and also connect the memory and inputs to the corresponding processor control signals. The upper 8-bit bank is called 'odd address memory bank' and the lower 8-bit bank is called 'even address memory bank'. Arrange the available memory chips so as to obtain 16-bit data bus width. The general procedure of static memory interfacing with 8086 is briefly described as follows: 1. For example, 4Kx8 or 4K byte memory contains 4096 locations, where each location contains 8-bit data and only one of the 4096 locations can be selected at a time. The semiconductor memories are organized as two dimensional arrays of memory locations.

The semiconductor RAMs are of broadly two types-static RAM and dynamic RAM. RAM (Random Access Memory) and ROM (Read Only Memory). 1 SEMICONDUCTOR MEMORY INTERFACING UNIT - III MEMORY AND IO INTERFACING Semiconductor memories are of two types, viz.
