WebFor memory access on the Z80 we will control DRAM timing with a combination of MREQ* and either RD* or WR*. We will design the system with a single 30 pin SIMM module. It will be able to support up to a 4MB SIMM. These SIMMs use bi-directional data pins, so we will have to use EARLY-WRITE on the SIMM. WebIn particular, static random access memory (SRAM)-based components (e.g., cache memories) are easily affected by process variation in NTC, resulting in large delay fluctuations.

http://www.piclist.com/techref/mem/dram/slide4.html WebSRAM is faster and typically used for cache. DRAM is less expensive and has a higher density and has a primary use as main processor memory/cache. Figure 1. DRAM stores one bit as memory using a transistor and a capacitor. With SRAM, each cell consists of six transistors (see Figure 2) and can store one single bit.
