Patent number: 9158683Abstract: A multiport memory emulator receives first and a second memory commands for concurrent processing of memory commands in one operation clock cycle. Data operands are stored in a memory array of bitcells that is arranged as rows and memory banks. An auxiliary memory bank provides a bitcell for physically storing an additional word for each row. The bank address portion of each of the first and second memory commands is respectively translated into a first and second physical bank address. The second physical bank address is assigned a bank address of a bank that is currently unused in response to a determination that the bank address portions are equal and the bank associated with the first bank address is designated as a currently unused bank for subsequently received memory commands in response to the determination that the bank address portions are equal. Simultaneous read and write operations are possible.Type: GrantFiled: August 9, 2012Date of Patent: October 13, 2015Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Aman A Kokrady, Shahid Ali, Vish Visvanathan, Vinod Joseph Menezes
