What is SRAM? It is a synonym of Static Random Access Memory. Some of the components of an SRAM circuit board are the Latching Element Signal Circuit or LED’s, SRAM chips and the Random Access Memories or RAMs. All these function together to form an efficient computer system that performs at its optimum when tasks are performed sequentially and in quick succession. Let us see how this memory operates in detail.
First of all we will explain what is sram. Static random-access memory, as the name suggests, is a memory where access is random and is stored in the chip. On the contrary, dynamic random-access memory is the memory where instructions are executed sequentially without waiting for the completion of other instructions. This is why it is faster than sram.
Let us study the working of sram. When an instruction pointer is deactivated, the corresponding instruction cell gets occupied by another processor register. This causes the processor to slow down since now the work of the microprocessor has to be shifted to another segment. When instructions for execution are supplied the corresponding sram area is activated. This then transfers the processed data to the targeted cache, making it available to the end-user.
The CPU’s work is divided in two segments/blocks: low layer and high layer. Since instructions for execution are not carried out immediately, the CPU carries out them at a later time. The work of the low layer is to maintain the access lists of the CPU’s random access memory and the instructions for execution of CPU’s low level code, such as shared memory and process libraries.
A random access memory is a non-volatile memory where random access is done without writing to the disk or to any other media. Non-volatile RAM is best suited for applications requiring random access to the data. This type of RAM is also called as volatile RAM since it is managed by an operating system through a control interface such as DOS. Volatile RAM is an excellent choice for PCs because of its ability to refresh unlike the RAM that uses a writing device. If your PC crashes, you can simply restart the computer and use its RAM to recover its performance.
In the traditional method of RAM architecture, the main memory is filled with random access data which is accessed by the CPU several times per second. In fact, the CPU’s scheduling algorithm relies on the data held in the main memory to determine when to execute a certain function. So if the data in the main memory is inaccessible or is corrupted, the CPU cannot perform its function and that causes it to slow down. The situation becomes worse when the system is not designed to use the e.g. SRAM.
In contrast to the non-volatile RAM, the sram is chip-mapped random access memory where the data resides permanently. A write operation is not required to access the data because the chip has a virtual address that ensures that only trusted software can write to the chip. The performance of the chip is therefore much better than the non-volatile type of RAM which depends on the write operation to access the data. So the performance of your PC depends largely on the information that is present in the sram.
The physical configuration of the chip prevents the CPU from accessing the sram directly. The operation requires an instruction decoded by the operating system which passes the address from the keyboard to the CPU. The PC reads the instruction and executes it into the memory where the data is stored temporarily. A latching circuit is present which latches the data after a period of inactivity. The current usage is controlled through the control register which monitors the number of reads and writes to the hard disk and other elements of the computer architecture.
