07 – Memory and Programmable Logic BY :M. Morris Mano Chapter 7 Memory and Programmable Logic 7.1 INTRODUCTION A memory unit is a device to which binary information is transferred for storage and from which information is retrieved whea & for processing. When data processing takes place, information from memory is transferred to selected registers in the processing anit. Intermediate and final results obtained in the processing unit are transferred back to be stored in memory, Binary information received from an input device is stored in memory. and information transferred to an output device is Wen from memory. A memory unit is a collection of cells capable of storing a large quanlity of b i i in formation. There are two types of de8tha t are used in digital systems: mndommcess memory (RAM) and read-only memory (ROM). RAM stores new information for later use. The process of storhg new infomation into memory is referred to as a menmy wrife eon. The process of transferring the stored information out of memory is referred to as a memory read operation. RAM can perform both write and read operations. ROM can perfom only the read operatim. This means that suitable binary information is already stored inside memory and can be retrieved or read at any time. However, that information cannot be altered by writing, ROM is a pmgmmabk logic We(PL D). The binary information that is stored within such a device is specified in some fashion and then embedded within the hardwam in a process is refd to as pmgming the &vice. Tbe word "pro%ramming" hm refers to a hardware pm cedure which specifies the bits that me inserted into the hardware cwfigumlio11 of the device. ROM is one example of a PLD. Otber such units are the programmable logic array (PLA), programmable array logic (PAL), and the field-programmable gate may (FPGA). A PLD is an integrated circuit with internal logic gates connected through electronic path that khave similarly to fuses. In the original state of the device, all the fuses ue intact+ Programming the device invoIves blowing those fuses along the paths that must be removed in ordm to obtain
