ROM types include: Programmable ROM (PROM) Erasable programmable ROM (EPROM) Electrically erasable programmable ROM (EEPROM) Flash Mask ROM The image below shows the function of both memory types in the hierarchy of a typical computer. Note that ROM is distinct from the computer's hard disk, ...
Microcontroller with memory content dependent conditional command decoder for accessing different memory typesIn a microcontroller () the command decoder () has access to at least one memory (). The command decoder may thus be adapted to decode at least one conditional command, while the result of...
Though the Cortex-M3 and Cortex-M4 processors do not have a cache memory or cache controller, a cache unit can be added on the microcontroller, which can use the memory attribute information to define the memory access behaviors. In addition, the cache attributes might also affect the operation...
IAR Embedded Work Bench IDE is used for programming MAXQ core-based microcontrollers. IAR™ C compiler (for MAXQ microcontroller) provides the option to define data objects or variables in the flash or SRAM locations. The compiler has special keywordspragma locationandpragm...
it can have multiple SRAM memory blocks placed in the SRAM region as well as the CODE region, and it can execute program code from external memory components located in RAM region.Microcontroller vendorscan also add their own system-level memory features, such as system-level cache, if needed...
Registers of 8051 Microcontroller If we perform any operation whether addition or subtraction, then these operations are unable to be performed directly in the memory, and therefore, are performed by using the registers. There are different types ofregisters in 8051 microcontroller. ...
Types of RAM There are two main types of RAM used in modern computers: SRAM (Static RAM): Faster but more expensive Used for cache memory in CPUs 2.DRAM (Dynamic RAM): Slower but less expensive than SRAM Used for main memory in computers ...
NOR densities range from 256 bits up to 2 Gb, which is also small. NOR is good at random read accesses, so it has a longstanding foothold in microcontroller applications, where it's used for code storage. Microcontroller firmware tends to be small. NOR chip prices range from below $1 to...
These features make the STM32F101xx high-density access line microcontroller family suitable for a wide range of applications such as medical and handheld equipment, PC peripherals and gaming, GPS platforms, industrial applications, PLC, printers, scanners alarm systems and video intercom. ...
12. In a system adapted to receive one of a plurality of different memory types, a method of determining a type of memory present, comprising: a) writing a sequence of data patterns to a memory in a page mode to a first sequence of column addresses; b) reading data from the memory in...
