WebSep 22, 2024 · Also on chip are the higher cache memories mostly made in SRAM or embedded dynamic random access memory (DRAM) technologies. Off-chip, further away from the CPU, you will mainly find DRAM chips for the working memory, non-volatile NAND Flash memory chips for storage, and tapes for long-term archival applications. Websupport two levels of cache: inner cache and outer cache. For the STM32F7 and STM32H7 series, only one level of cache (L1-cache) is supported. The cache control is done globally by the cache control register, but the MPU can specify the cache policy and whether the region is cacheable or not. 2.1 Memory model

WebSRAM (Static Random-Access Memory) is a form of RAM that is used to store static data. It means that data stored in SRAM is active for as long as the computer system is powered up. When there are power outages, however, data in SRAM is lost. Characteristics of SRAM It does not need to be refreshed. It outperforms DRAM. It’s not cheap.

It also requires less power than DRAM, but it is also more expensive. Engineers use it in more limited ways in embedded systems.
WebCH - Assignment 1. 5.0 (1 review) What three characteristics are true about SRAM and DRAM? -SRAM and DRAM both need to be refreshed with the same frequency. -Both are considered volatile because they only hold data while power is on. -SRAM is faster than DRAM because it does not need to be refreshed. -DRAM is closer to the CPU than …
