ADN-ZB Kasper 6.4.1989 Bez. Gera: Zum Tag des Metallarbeiters 1989-Der dynamische 1-Megabit-Schreib-Lese-Speicher U 61000 aus dem Kombinat VEB Carl Zeiss Jena ist der erste Schaltkreistyp der Zeiss-Fertigung auf der Basis einer n-Wandler-CMOS-Technologie im Strukturniveau 1 Mikrometer. Technologische Spezialausrüstungen des Elektronikmaschinenbaus - unerlässliche Voraussetzung für die Produktion hochintegrierter mikroelektronischer Bauelemente - entstehen im Betrieb für optischen Präzisionsgerätebau des Zeiss-Kombinates.

What Is RAM? Baby Don’t RAM me no more(DRAM, SRAM & SDRAM)

Not this type of Ram ->
182511793

RAM stand for Random Access Memory, and is typically volatile meaning that the data is deleted once the is no power.

There are three common types of RAM(not including the animal) DRAM, SRAM & SDRAM.

RAM has recently increased in price due to Crypto Mining and a lack of supply

DRAM:

  • stands for Dynamic Random Access Memory
  • Its Volatile which means that any data stored on the DIM will be lost if there is a loss of power. This makes RAM useful for programmes which want to temporarily store data which can be called upon quickly and doesn’t need to be permanently stored.

SRAM:

  • Static random-access memory
    • Unlike  DRAM, SRAM is not need to be refreshed
  • Consumes a low amount of power
  • Expensive
  • small capacity compared to DRAM
  • Some versions can be non-volatile meaning that the data is saved even if power is lost.

 

SDRAM:

  • Synchronous dynamic  Random Access Memory
  • DDR SDRAM(Double Data rate synchronous dynamic Random access memory)
  • Different iterations each improving on the last such as voltages and clock speeds :
    • DDR 1- bus clock: 100-200 MHz
      • Voltage: 2.5
    • DDR 2- bus Clock: 200- 533.33 MHz
      • Voltage: 1.8
    • DDR 3- Bus Clock: 400–1066.67 MHz
      • Voltage: 1.5
    • DDR 4- Bus Clock: 1066.67–2133.33 MHz
      • Voltage: 1.05
