DRAM 41256 PDF - Dynamic random-access memory (DRAM) is a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit. DRAM is essentially the same as SRAM, except that it retains data for only 2 or 4 ms on an integrated capacitor.
Simple observation: reading out entire row and throwing out all but one bit is inefficient. Its sophisticated low pass filter will not end in the normal applications due to the high sampling rate (25~50kHz). By the mid-1980s, these had given way to single voltage DRAM such as the 4164 and 41256 with the result of improved reliability. dram 41256 pdf August 10, 2019 admin Dynamic random-access memory (DRAM) is a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit.

Problem: DRAM bandwidth (bits/second) has not kept up with CPU speed increases over the years. It provides continuously adjustable delay time up to 0.8/0.2 seconds at a sampling rate of 25kHz when combined with an external DRAM (41256/4164).

After 2 or 4 ms, the contents of the DRAM must be completely rewritten (refreshed). Refresh period is extended to 4 milliseconds, and during this period each of the 256 rows must be strobed with RAS in order to retain data.
