Part Number Description
MSM514252A
manufacturer
OKI electronic componets
DRAM / FAST PAGE MODE TYPE
The MSM514252A is an 1-Mbit CMOS multiport DRAM composed of a 262,144-word by 4-bit dynamic RAM, and a 512-word by 4-bit static serial access memory, SAM port. The RAM port and SAM port operate independently and asynchronously. The MSM514252A supports three types of operations: random access to and from the RAM port, high speed serial access to and from the SAM port and bidirectional transfer of data between any selected row in the RAM port and the SAM port. The RAM port and the SAM port can be accessed independently except when data is being transferred between them internally. FEATURES • Single power supply of 5 V ± 10% with a built-in VBB generator • All inputs and outputs: TTL compatibl...
