74LS603 Memory Refresh Controllers IC (74603) DIP-20 Package
The LS603A memory refresh controllers contain one 8-bit synchronous counter, nine 3-state buffer drivers, four RC controlled multivibrators, and other control circuitry on a single monolithic chip. These devices are designed to provide RAS-only refresh on 4K, 16K, and 64K dynamic RAMs. The LS600A and LS601A provide transparent refresh while the LS603A provides cycle steal refresh. in addition, a burst-mode timer is provided to warn the CPU that the maximum allowable refresh time is about to be violated.
